Python 3.14 tests failing with AssertionError: assert '(?s:foo[^/]*)\\z' == '(?s:foo[^/]*)\\Z' #381
Description
Recently noticed that all CI runs using Python 3.14 are failing with AssertionError: assert '(?s:foo[^/]*)\\z' == '(?s:foo[^/]*)\\Z'.
This includes the jobs test (3.14, ubuntu-latest) and collateral (diffcov).
Complete error:

> uvx --python=3.13 python -c "import fnmatch; print(fnmatch.translate('foo*'))"
(?s:foo.*)\Z
> uvx --python=3.14 python -c "import fnmatch; print(fnmatch.translate('foo*'))"
