Package validation fail

[maridematte]

Describe the bug

When updating our PackageValidationBaselineVersion the build fails on package validation. However when running our build with /p:ApiCompatGenerateSuppressionFile=true to update the files as instructed, the only differece in the output is that the command deleted the comments we had on the xlm files:

You can see it in https://github.com/dotnet/msbuild/pull/10116

Repro

• Download MSBuild repo
• Update the PackageValidationBaselineVersion to 17.10.4 (the new release version)
• Run .\build.cmd -c Release -pack /p:ApiCompatGenerateSuppressionFile=true from msbuild repo source.
• Check the differences in the xml files.
