chore(bugbot): Add rules to flag test-flake-provoking patterns

[Lms24]

We need to get a grip on our test flake situation again. Currently, CI flakes on almost every initial run, which is especially painful when cutting releases. This PR adds a few rules for bug bot to look out for anti patterns that are likely to introduce new test flakes.
