Update Rails to 7.2 and misc. non-major dependency updates (#80)

General non-major packages updates.

This includes a Rails 7.1 -> 7.2 update. Run `bin/rails app:update` and pick out
appropriate changes for the framework.

The RuboCop RSpec checks are now complaining for some reason, so exclude a few
rules that we are currently not following.
