They are only surfaced under pytest 8.4, with `pytest-cov` and
`pytest-xdist` being both active [[1]]. Or equivalent situations

This is a follow-up for #16015 which attempted ignoring the warning
on the runtime level in pytest. Instead, the patch tells `coveragepy`
not to emit said warnings in the first place.
