So, we previously set this to 4 but afaict at max, we test 3 browsers. Some tests potentially even only run on Chrome. So I think it's ok to reduce this in favour of more often running each test. My super unscientific testing says we currently run way shorter than 30min.

Our flaky test detector uses a couple of heuristics to determine how many times each changed test should be run. We previously relied on the assumption that one test path (file) only contained one file. In some cases this is not true because it's totally valid to contain multiple

test runs in one file.This PR adds a small test detection heuristic to the detector to roughly count the number of tests in a file. This should reduce the number of times each test is running in case files with multiple tests have changed. Furthermore, this PR also refactors the run count determination logic a bit to make it easier to understand.
An example of this is a PR of mine (#11631) where the test detector would run into the 60 minutes timeout because each changed test file contained multiple (~5) test files. So the actual number of tests would be 5x higher than what our heuristic assumed.
