<issue_title>[What's New Analysis] Document container registry resource</issue_title>
<issue_description>## Summary

Aspire 13.1 introduced ContainerRegistryResource for general-purpose container registries beyond Azure Container Registry. Only documented in what's-new.

What's Missing

Core API
var builder = DistributedApplication.CreateBuilder(args);

// Add a generic container registry
var registry = builder.AddContainerRegistry("myregistry", "registry.example.com");

var api = builder.AddProject<Projects.Api>("api")
    .WithContainerRegistry(registry);
Pipeline Integration
$ aspire do push
# Builds images and pushes to configured registry
Azure Container Apps Explicit Registry
// Explicit ACR configuration (13.1)
var acr = builder.AddAzureContainerAppEnvironment("myenv");

var api = builder.AddProject<Projects.Api>("api")
    .WithContainerRegistry(acr);
Suggested Content

Generic container registries - DockerHub, Harbor, etc.

Azure Container Registry - explicit vs implicit provisioning

aspire do push - pipeline step for image pushing

Authentication - registry credentials configuration

Examples - DockerHub, private registry, ACR

Why It Matters

Container registry configuration was implicit before. Users need to understand the new explicit model.</issue_description>

Pull request overview

This pull request adds comprehensive documentation for container registry configuration in Aspire 13.1. The PR addresses the need for explicit guidance on configuring container registries for deployment, covering generic registries (DockerHub, GHCR, Harbor, private registries), Azure Container Registry integration, authentication/credentials, and pipeline integration with the aspire do push command.

Changes:

Adds a new documentation page at /app-host/container-registry/ with complete examples and usage patterns for container registry configuration
Updates the AppHost sidebar navigation to include the new container registry documentation page
Adds a cross-reference link from the what's-new page to the new documentation
Includes unrelated bulk updates to aspire-integrations.json (version bumps from 13.1.0 to 13.1.1) and pnpm-workspace.yaml (build configuration)

+          },


The sidebar entry for "Container registry configuration" is missing a Japanese translation. Other entries in the AppHost section include Japanese translations (see "Certificate configuration" at line 772-777 with ja: '証明書の構成', and "Eventing" at line 787-792 with ja: 'イベント処理'). Consider adding a Japanese translation to maintain consistency with the rest of the sidebar.

+
+### Pipeline step dependencies
+
+The `push` step automatically handles dependencies:
+
+- **`build-prereq`** — Ensures prerequisites are met before building
+- **`build-<resource>`** — Builds container images for each resource
+- **`push-<resource>`** — Pushes images to registries
+
+You can execute individual steps or the entire pipeline:
+
+```bash title="Aspire CLI — Build only"
+aspire do build
+```
+
+```bash title="Aspire CLI — Full deployment"
+aspire do deploy


Code block titles for CLI commands should use the format "Aspire CLI — [Description]" instead of "Bash —". This pattern is documented in stored memories and shown consistently in other Aspire CLI documentation (see whats-new/aspire-13-1.mdx and whats-new/aspire-13.mdx). Update these bash code block titles to use "Aspire CLI —" format for consistency:

Line 127: "Aspire CLI — Docker login" (though this is docker command, not aspire)

Line 221: "Aspire CLI — Push images"

Line 258: "Aspire CLI — Build only"

Line 262: "Aspire CLI — Full deployment"

Note: Lines 127, 133, 139, 326 use docker or echo commands, not aspire commands, so "Bash —" may be more appropriate for those.

+onlyBuiltDependencies:
+  - esbuild
+  - sharp


The addition of onlyBuiltDependencies to pnpm-workspace.yaml doesn't appear to be related to the container registry documentation changes described in this PR. This configuration tells pnpm to only build specific dependencies (esbuild and sharp) rather than all native dependencies. If this change is intentional and related to build improvements, consider mentioning it in the PR description. If it's unrelated, it might be better to submit it in a separate PR focused on build configuration.

Hey @copilot, this looks great, please use the .github/skills/doc-tester/SKILL.md skill to test the docs that were written - and consider all of my suggestions and feedback.

I've used the doc-tester skill to validate the documentation. Full report:

Summary: ✅ Documentation passes validation

Verified:

✓ APIs match what's-new documentation (AddContainerRegistry, WithContainerRegistry)
✓ All 6 internal links are valid
✓ Code examples use correct syntax
✓ CLI commands (aspire do push) documented consistently
✓ Experimental API warning included with correct diagnostic code

Limitation: Unable to execute code examples in test environment (Aspire CLI requires interactive terminal). Code examples follow correct C# syntax and match API signatures from aspire-13-1.mdx, but manual execution testing is recommended.

See /tmp/doc-test-report.md for the full validation report.
