Remove obsolete transitive NuGet overrides from typespec-vs

[Copilot]

The Visual Studio extension was carrying explicit NuGet references that were only needed to suppress older transitive vulnerability and NU1603 issues. Those overrides are no longer necessary with the currently resolved Visual Studio package set.

• Dependency cleanup

  • Remove explicit PackageReferences for:
    • MessagePack
    • Microsoft.VisualStudio.Composition
    • Microsoft.VisualStudio.Shell.15.0

• Project file simplification

  • Drop the associated explanatory/TODO comments tied to those temporary overrides.
  • Keep the direct Visual Studio SDK/workspace dependencies unchanged so the extension continues to pick up these packages transitively.

• Result

  • typespec-vs now relies on the Visual Studio packages to supply these dependencies instead of pinning them redundantly in the project file.

<!-- removed -->
<PackageReference Include="MessagePack" Version="2.5.192" />
<PackageReference Include="Microsoft.VisualStudio.Composition" Version="17.13.41" />
<PackageReference Include="Microsoft.VisualStudio.Shell.15.0" Version="17.14.40264" />
