Fix the issue with libgit2sharp blocking newer .NET versions

The single-file build functionality in .NET 5 did not work well with earlier versions of libgit2sharp. Let's see if our build works with this version and .NET 5 or .NET 6.
For discussion of the errors we got when trying .NET 5 with earlier versions of libgit2sharp, see libgit2/libgit2sharp#1857, libgit2/libgit2sharp.nativebinaries#111,
libgit2/libgit2sharp.nativebinaries#119, dotnet/sdk#3685, and dotnet/runtime#36590
