FIX: Add arm64 Support for devcontainer

[spencrr]

Description

Fixes the devcontainer to support both amd64 and arm64 architectures. Previously, the Dockerfile and docker-compose.yml hardcoded linux/amd64, which caused issues on ARM-based machines.

Changes

• Removed --platform=linux/amd64 from the FROM instruction in .devcontainer/Dockerfile so Docker uses the host's native architecture.
• Removed platform: linux/amd64 from .devcontainer/docker-compose.yml.
• Made the Microsoft apt repo arch-aware by replacing the hardcoded arch=amd64 with arch=$(dpkg --print-architecture).
• Updated mssql-tools to mssql-tools18, which adds arm64 support (the older mssql-tools package was amd64-only). Removed the redundant unixodbc-dev install (already installed in the earlier apt-get block).

Tests and Documentation

• No test or documentation changes required; this is an infrastructure/devcontainer-only change.
• Verified the devcontainer builds and starts successfully on arm64.

Pull request overview

This PR updates the devcontainer configuration to build and run on both amd64 and arm64 hosts by removing hardcoded amd64 platform targeting and making Microsoft repo/package installation architecture-aware.

Changes:

• Removed linux/amd64 platform pinning from the devcontainer Dockerfile and docker-compose configuration.
• Made the Microsoft apt repo entry use the host architecture and installed MSSQL tooling only on amd64.
• Added Rust toolchain installation to support building Python dependencies on platforms without prebuilt wheels (e.g., arm64).

File	Description
.devcontainer/docker-compose.yml	Removes amd64-only platform pin so Compose uses the native host architecture.
.devcontainer/Dockerfile	Removes amd64-only base image constraint; makes Microsoft apt repo arch-aware; conditionally installs MSSQL tools; adds Rust toolchain.

I'm approving hoping this works on Mac. @riyosha can perhaps confirm.

I checked this, the devcontainer setup works on Mac!

@romanlutz I tried out on an M1 Mac (arm64) - maybe we can add a macos github actions smoketest workflow🤔
