Update coveragepy and use sys.monitoring interface

[danielhollas]

In general, collecting code coverage (pytest --cov) makes the test suite run quite a bit slower.
However, the new version of coveragepy allows to use a different approach based on the new sys.monitoring interface (3.12+) which is much faster (almost free), see https://nedbatchelder.com/blog/202312/coveragepy_with_sysmonitoring.html

https://coverage.readthedocs.io/en/7.10.7/config.html#run-core

Besides that, if TYPE_CHECKING: blocks are now automatically ignored, resulting in a "increase" of overall coverage (less uncovered lines of code).

This PR drops the runtime of the Py3.9(psql) job from 26 to 20 minutes! 🎉

Sorry for taking so long to get back here, had some other tasks going on. Thanks for the changes! Just wondering if we can already pin coverage it to 7.11 by now? Apart from that, LGTM.

[GeigerJ2]

By now, could even be 7.11 (released 15 Oct)? 🤔

[danielhollas]

We can't put 7.11 as minimum version since it dropped Python 3.9 support. But I've updated the lockfile so that this version is used with Python 3.13, which we use in CI.

But ultimately, we don't need to depend on coverage directly, since we're running in via pytest-cov plugin. So I've bumped pytest-cov plugin to latest version, which sets the minimum coverage version to 7.10.6: https://pytest-cov.readthedocs.io/en/latest/changelog.html#id1

Looks like a flaky test, I've rerun the job.
