Ruby3

[anitagraham]

This PR (and its matching PR on https://github.com/refinery/refinerycms-i18n ) allow refinerycms to run with Ruby 3.

It has been tested with Ruby 3.1.2 and Rails 6.1.6.1 Will shortly be tested on Rails 7.

One test failure on /resources, which I haven't been able to fathom.

Tests failing:

I have seen some of these errors during testing, but thought I was past them. Many seem to be timeouts, and then the reporting of timeouts seems to be a problem too.

There are many variations of:

 1.1) Failure/Error: **visit refinery.admin_images_path**
          RuntimeError:
            Rack application timed out during boot
          # ./core/spec/system/refinery/admin/xhr_paging_spec.rb:19:in `block (3 levels) in <module:Refinery>'

and I saw some other reporting of timeouts on visit, as a result of changes to bundler, I think.

Also frequently seen (below), which seems to be an error reporting timeouts. It occurs every minute during a run.

Thank you for looking at this

Is there any update on the status of this PR? I need to upgrade to ruby 3.2.1 and rails 6.x because I need to upgrade to the newest cflinux4 buildpack and no previous versions of ruby are supported. I currently use refinerycms with ruby 2.5.5 and rails 5.x.

I think this merge will help me upgrade to the versions of ruby and rails mentioned above. Thank you.

@pdornfel I'd really love to merge this but CI isn't happy. The corresponding PR for refinerycms-i18n is failing on Ruby 3.0 and 3.2, but not 3.1 🤔 https://github.com/refinery/refinerycms-i18n/pull/104

Any help you or anyone else can lend with figuring out why this is happening would be greatly appreciated. Right now, I suspect the routing-filter gem we use.
