CompatHelper: bump compat for "Compose" to "0.9"

[github-actions]

This pull request changes the compat entry for the Compose package from 0.7.4, 0.8 to 0.7.4, 0.8, 0.9.

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.
