Accept packages with mhs-options (MicroHs options) #1446

Uploading my package to Hackage failed due to mhs-options:

https://github.com/hspec/hspec/actions/runs/20167421952/job/57894166588

This is a blocker for me as without these options my package does not build with MicroHs.

Also note that cabal check only warns on mhs-options, it does not fail with "Hackage would reject this package".
