I couldn't figure out the best area label to add to this PR. If you have write-permissions please help me learn by adding exactly one area label.

This is failing because the DARC updated the versions based on the main branch in mono/linker (so version ending with .2) which is published to the dotnet7 feed. But the runtime repo main is still setup to use dotnet6 feed which has a higher version from the release/6.0.1xx branch in mono linker (version ending with .3).

What's the plan for feeds in runtime main? Shouldn't they be updated to dotnet7 feeds?

Adding the NET7 feeds is done in #57627, once that PR is merged this should be unblocked.

This should be unblocked now.
