CompatHelper: bump compat for HypothesisTests to 0.12, (keep existing compat)

[github-actions]

This pull request changes the compat entry for the HypothesisTests package from 0.10.4, 0.11 to 0.10.4, 0.11, 0.12.
This keeps the compat entries for earlier versions.

Note: I have not tested your package with this new compat entry.
It is your responsibility to make sure that your package tests pass before you merge this pull request.
