ActionPack (Rails) 7 support

[pilaf]

Rails 7 removed ActiveSupport::Dependencies.safe_constantize (commit), which Spyke depends on, essentially breaking Spyke on Rails 7.

This PR fixes it by detecting if the old method still exists, and reverting to the new ActiveSupport::Inflector.safe_constantize if not.

Thanks a lot for submitting this @pilaf!

As the comment says, this bit was more or less stolen "as-is" from Rails.

I think maybe we can follow the recommendation in the PR and use the public API of string.safe_constantize instead.

I've pushed a commit, could you maybe give it a shot to see if it works for you?

(and I guess I need to get tests set up for multiple versions of Rails 😅 )

Thanks again for spotting this! 👌

Hi @balvig, thanks for the quick reply!

You're right, for some reason I thought String#safe_constantize was a new addition in replacement of the AS::Dependencies method, but looking closely it's been there since the Rails 3 days.

I ran the tests using your commit against versions 4, 5, 6 and 7 of ActiveSupport, and it seems to work on all of them.

For versions 4 and 5 of ActiveSupport one test failed, but it seemed completely unrelated to this issue.
