argparse.FileType is deprecated in Python 3.14 #591
Description
This now raises PendingDeprecationWarning:

charset_normalizer/pyproject.toml
Lines 62 to 64 in 0237181
I think it will cause the test suite to fail with 3.14. I experienced this in Fedora Linux, where we are already preparing Python 3.14.
