Ruby 3 support

[honzasterba]

I have taken the changes from https://github.com/matthewrudy/memoist/pull/92 fixed up the code and added tests and CI runs for Ruby 3 and 3.1

The solution for ruby3 kwargs is to add the hash of passed kwargs in its array form the the cache ivar.

Thanks for doing this! Maybe we should make this against https://github.com/memoist/memoist ? Or possibly @sebjacobs would be able to approve this?
