v3.0.0a7

3.0.0a7 is an alpha release, other breaking changes will be added before the official 3.0.0 release. Compared to 3.0.0a6, this alpha brings mainly python 3.12 compatibility but also the changes you would usually expect with a minor of regular size. It will requires some changes to the configuration that should be automated when 3.0.0 is out, but aren't yet. Those changes can make the configuration incompatible or at least not equivalent if used with pylint 2.x.
