[Microsoft.DotNet.Build.Tasks.Archives] Allow override to use tar.exe on windows to produce tar.gz files.

I would like an option in Microsoft.DotNet.Build.Tasks.Archives where one can produce tar.gz files on Windows like how the package produces them on both linux and macos for consistency. Currently the way one has to set it up is to have special cases for zip for the odd OS known as Windows. With tools on Windows that allows one to extract from tar's I see no reason to not have an option to override the inability to use the tar application that is now shipping in Windows 11. For those without tar, I think it is fine to fail.
