CompatHelper: bump compat for Aqua to 0.8 for package test, (keep existing compat)

[github-actions[bot]]

This pull request changes the compat entry for the Aqua package from 0.7 to 0.7, 0.8 for package test. 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.
