Fix the Windows publish bundles for the Avalonia project layout

publish.ps1 is a WPF-era script that was never updated for the current
tree, and the "Publish x64/arm64" CI step aborted on two stale things:

- It published ./ILSpy.BamlDecompiler/ILSpy.BamlDecompiler.csproj, which
  does not exist here (the BAML library is ICSharpCode.BamlDecompiler and
  already ships transitively via the ILSpy dependency graph) -> MSB1009.

- It publishes the ReadyToRun plugin RID-specifically without restoring
  again, but the plugin declared no RuntimeIdentifiers, so the RID-less
  solution restore produced no win-x64/win-arm64 assets -> NETSDK1047.

Drop the dead BamlDecompiler lines and give the plugin RuntimeIdentifiers
mirroring ILSpy.csproj, so it restores and publishes for every platform
the host supports (the plugin is pure managed and RID-agnostic).
