fix: Support older version of Pundit

[rickychilcott]

Description

Pundit 2.2.0 changes the Module that is required to be included, which is a breaking change. Since Pundit 2.1.x is still very viable for most apps, support both options.

Not sure what you think of this one @adrianthedev.

I'm surprised that varvet/pundit@4d9b584 wasn't considered a breaking change (i.e. bumping to Pundit 3.0), but either way, I can't currently fix all of my OTHER dependencies to jump to Pundit v2.2 yet.

Does this simple version work or would you rather a Pundit version check?

Hey @rickychilcott. Yeah, this might work. It seems I haven't thought about this change as being a breaking change, but what you're saying makes sense.

I'll check it out and merge this before Monday's release.
