Expose configuration via class-level method and fixes EnumArrayScopeListMixin

[anthony0030]

On a project I'm working on, we need access to the config for the acts_as_list.
I also made sure all the tests are successful and added the appropriate tests for the new functionality that this PR adds.
It took me some time to get the DB to function, I used sqlite.
It would be great if there was some official documentation on how to set up the dev environment.
If you need any adjustments to this PR, please let me know, and I will make them ASAP.

If you accept this PR, please also publish it to Gemhub so my colleagues can easily use it.

Hi @anthony0030, thanks for this. The dev environment can be tricky. Testing different databases relies on using ENV variables. Take a look at the GitHub Actions file for a few clues. If you'd like to put together some docs on development in a PR that would be helpful. Also, if you're only starting out with ActsAsList take a look at my other library Positioning as it might also do what you want. I'd be open to allowing configuration introspection there.

The test failures here are around needing to require logger now in older versions of rails. You can probably just require it in the test setup somewhere.

Hi @anthony0030, just get the test suite green and I can merge it. It might well work if you rebase to master.

[anthony0030]

Hi @brendon, I rebased on master like you told me to. Also the tests seem to run locally now.

Nice :) It all tests green. Can you add a changelog line for me in the Unreleased section please. Be sure to attribute yourself :D I can then merge and release this.

[anthony0030]
