Lately I stumbled upon several places where URLs are pointing to e.g. https://docs.pytest.org/latest/tmpdir.html while this is a 404 nowadays and should instead be https://docs.pytest.org/en/latest/tmpdir.html

(IIRC this affects more than just the tmpdir docs since I stumbled upon some 404s when looking for docs)
Reporting here-by as follow up on IRC, thanks for pytest!
