pylint 3.0 deprectations

Changelog: https://pylint.pycqa.org/en/latest/whatsnew/3/3.0/index.html#summary-release-highlights

remove `__implements__`:
That attribute is apparently from a rejected PEP. They say to inherit
from BaseChecker, which we are already doing.
https://github.com/pylint-dev/pylint/pull/8404

check_messages -> only_required_for_messages:
Seems straightforward instructions. I haven't actually tested it.
https://github.com/pylint-dev/pylint/pull/8409

remove emptystring extension:
Looks like this has been replaced by https://pylint.readthedocs.io/en/stable/user_guide/messages/convention/use-implicit-booleaness-not-comparison-to-string.html
Which is disabled by default but we have `enable=ALL`, so I guess that means
we indeed have it enabled.

And update changelog URLs.
