Wrap examples with Rails executor

This recreates rspec#2712 since the GHA logs are no longer available which we need to address this issue. We should be wrapping the Rails examples with the executor to mimic what Rails v7 does (as noted in rspec#2713) to properly reset state. This has been tested in a test suite for an app but we need to address what issues there is within rspec-rails. This change request originated from rspec#2503 and rspec#2752 which the latter is meant as a temporary fix since this is the expected way to reset state.
