replace flaky with pytest-rerunfailures (#10335)

* Revert "limit pytest version to <8.1 (#10334)"

This reverts commit bc95b650a4.

* replace flaky with pytest-rerunfailures

`flaky` project seems to be unmaintained (see box/flaky#192).
`pytest-rerunfailures` seems to be maintained under `pytest-dev`
and tests 5 minor releases of pytest.

Note that this plugin is not compatible with `flaky` plugin.
You will have to uninstall it if it exists.
