Upgrade tbump to 6.7.0

[Pierre-Sassoulas]

When upgrading tbump to 6.6.1 in #5561, it broke the main branch. @DanielNoord fixed the root issue with #5566, and the change was reverted in #5567. Now we need to revert the revert and fix the primer.

We could add tbump to the primers. I think it's a small project. I realized some project takes a lot of time like django, but we can add small project without too much drawbacks.

I'm not sure the break is actually in tbump. The stdlib primer was failing after this change, so running over tbump likely wouldn't have catched this issue. I do wonder though why a change to tbump broke the stdlib primer..

It only happened in python 3.9 and 3.10. Here's the traceback so we don't have to search for old github actions jobs later:

Looking at the stacktrace and what I changed in pylint-dev/astroid#1321 I think this might actually be a "requires astroid update". We should at least try and see if this gets fixed with an astroid version that includes that fix. It seems as if this might be the type of issue that was solved with the initial fix in pylint-dev/astroid@6ca01e0 but which doesn't work anymore on setuptools >= 60.0.0.

[Pierre-Sassoulas]

My next goal is to release astroid 2.9.1, let's see how it goes after this is done.

The primer tests do seem to work in #5600. The CACHE_VERSION bump might have fixed it.

We upgraded tbump to 6.6.1 in #5561, I4m going to rename this to 6.7.0 and put it in the milestone for pylint 2.14 as we need to drop python 3.6 first.

[Pierre-Sassoulas]

The required tbump version is now 6.8.0, it was done automatically by dependabot in #6259 and #5600 following the migration from python 3.6.
