CompatHelper: bump compat for Nemo to 0.41, (keep existing compat)

[github-actions]

This pull request changes the compat entry for the Nemo package from 0.38, 0.39, 0.40 to 0.38, 0.39, 0.40, 0.41.
This keeps the compat entries for earlier versions.

It is your responsibility to make sure that your package tests pass before you merge this pull request.
