[Bundles] Bundle generation fails with local repositories with relative path in nuget.config

[Nefarion]

When running dotnet ef migrations bundle, the process fails for me with an error message:

C:\Program Files\dotnet\sdk\6.0.100\NuGet.targets(130,5): error : The local source '<>\AppData\Local\Temp\v2szyjyq.rk0\lib' doesn't exist. [<>\AppData\Local\Temp\v2szyjyq.rk0\efbundle.csproj]

I managed to interrupt the process so the folder does not get deleted, and looked at the resulting folder.

The issue is, the nuget.config file gets copied from the source project, and my nuget.config file looks like this:

<configuration>
  <packageSources>
    <add key="LibRepo" value=".\lib" />
  </packageSources>
</configuration>

If i replace the relative path with an absolute one, everything works fine.

Maybe it is necessary to do this transformation on the copied nuget.config?

Notes from triage: To fix this we could either parse and resolve to absolute paths, or if this proves fragile/complex, then try ignoring any failed sources.
