Relax activesupport dependency to support rails 8

[drobny]

In addition, upgrade the GH actions checkout dependency to the latest so it runs on supported version of node

@drobny thank you. I am not dogmatic about how many unrelated changes would be acceptable for a PR but in general, I'd recommend upgrading actions independently from, say, library dependencies.

But this PR can go in as is.

@drobny I assume it would be a good idea to produce a new patch release soon to allow for easier adoption of Hutch with new Ruby on Rails versions. Am I correct?

Yes I think that would be ideal 👍 Thanks again for your swift review and ongoing maintenance of hutch 😄

@drobny understood. You should have a new version up on RubyGems by Monday :) Have a good one and thank you for contributing!

Done.
