Fix gitlab CI setup to run tests on next major/minor

Proven in https://git.drupalcode.org/issue/scheduled_transitions-3456090/-/jobs/19... the 11.x deploystack is running on 10.3.0

However, this new method isn't running any tests on 11.x....

So NEXT_MAJOR wasn't running because of our core_version_requirement, see the grep/sed in the log output:

$ grep -q "\^11" *.info.yml || (grep -q "\^10" *.info.yml && sed -i "s/\^10/\^10 \|\| ^11/" *.info.yml)

I don't think it's safe to say '>=10.3' - we should be defining this more strictly (and following what the general case is in the community with defining specific core versions.

One more deprecation to fix before we get to the failure fixed by 🐛 ScheduledTransitionsSettingsForm::__construct is missing $typedConfigManager results in ArgumentCountError Needs review
