…ons/checkout-3

Bump actions/checkout from 2 to 3

Add Ruby 3.2 support

This will run CI on PRs and merges to master. Also we define a dummy job
which we can enforce during reviews.

main got moved to puppet 8 which now requires Ruby 3.1 or newer.

There was a fuckup with concurrent-ruby 1.2.0 release which dropped a
private API that puppet used. newer Puppet versions (7.22 and newer)
depend on concurrent-ruby < 1.2.0. We need to force ~> puppet 7.22
installation to ensure bundler doesn't pull in a newer concurrent-ruby
and older Puppet version.

Puppet 7: Ensure we test against 7.24 or newer

Add Puppet 8 to CI matrix

Release 3.4.0
