Move field type into Reference group in new Drupal 10.2 field UI

Started a merge request, but this is a bit of a chicken/egg situation together with paragraphs.

To be able to promote paragraphs to a top-level option, we need it as a preconfigured option that we then move out.

But by no longer promoting ERR to a top-level option/separate category, we don't really want to do preconfigured options anymore.

Should we adapt gitlab ci to run tests on D9 and next minor?

variables:
  OPT_IN_TEST_PREVIOUS_MAJOR: 1
  OPT_IN_TEST_NEXT_MINOR: 1

So, here's what this does now:

* Either old string category or reference, reverted the logic from before, so we can remove the alter hook in the future, and the default is the new one.
* Extend the preconfigured options to include a (revisions) suffix to make that clearer. We kind of need this still so paragraphs can move it out and only very few entity types use the common revisions refernce flag, so most people won't see that
* Change the default option to Other (revisions).

Will see what tests think about it, some explicit test coverage of this would be neat too, make sure the new labels show up as expected.

Fixed that test fail, added a check on the label and merged.

Automatically closed - issue fixed for 2 weeks with no activity.
