Steps to reproduce

After the breaking change in native command execution in pwsh 7.3 our scripts stopped working with msbuild. This happens when setting a property-value of an msbuild script containing a semicolon or comma. For this the raw part of the property assignment must contain quotes: /pCategory="CI,Nightly"

Without the quotes /pCategory=CI,Nightly the result is: MSBUILD : error MSB1006: Property is not valid. Switch: Nightly
Thats because you can set multiple properties like so: /p:Category=CI,OtherProperty=OtherValue

This command now produces different results (old pwsh without quotes in value of msbuild script, pwsh 7.3 with quotes):
& 'MSBuild.exe' @( 'D:\test.xml', "/p:Category="CI,Nightly"")

MSBuild-Script:

<Project DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
	<PropertyGroup>
		<Category>Default</Category>
	</PropertyGroup>

	<Target Name="Build">
		<Message Importance="High" Text="Category: $(Category)" />
		<Message Importance="High" Text="Finished" />
	</Target>
</Project>

With the new quoting rules it is impossible to satisfy the msbuild commandline without using Start-Process. Which has other problems which needs workarounds: dotnet/msbuild#2269

Please add msbuild to the list of legacy commands.
