CompatHelper: bump compat for "Distributions" to "0.23"

[github-actions]

This pull request changes the compat entry for the Distributions package from 0.21, 0.22 to 0.21, 0.22, 0.23.

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.
