dotnet-msbuild: move AITools.BinlogMcp source to dotnet-tools feed

[JanKrivanek]

Follow-up to #673. The AITools.BinlogMcp package was relocated from the dnceng dotnet-eng public feed to the dnceng dotnet-tools public feed, so the plugin can no longer restore it.

What changed

• plugins/dotnet-msbuild/plugin.json — --add-source URL updated to https://pkgs.dev.azure.com/dnceng/public/_packaging/dotnet-tools/nuget/v3/index.json.
• plugins/dotnet-msbuild/skills/binlog-failure-analysis/SKILL.md — fallback note updated to reference the dotnet-tools feed.

Verified the package resolves on the new feed:

> dotnet package search AITools.BinlogMcp --source https://pkgs.dev.azure.com/dnceng/public/_packaging/dotnet-tools/nuget/v3/index.json --prerelease
| Package ID        | Latest Version        |
| AITools.BinlogMcp | 1.0.0-preview.26270.7 |

⏰ timeout — run(s) hit the (360s) scenario timeout limit; scoring may be impacted by aborting model execution before it could produce its full output (increase via timeout in eval.yaml)
