fix: update twine to address importlib-metadata issue

Update twine to version 5.1.1 or higher to address a bug stemming from
twine's reliance on deprecated behavior, which was removed from
importlib-metadata in version 8.0.0.
For more details, see:
- python/importlib_metadata@a970a49
- pypa/twine#977

The plugin currently uses twine version 4.0.2, which depends on the
latest version of importlib-metadata (>= 3.6).
Consequently, it is impacted by the breaking changes introduced in
importlib-metadata version 8.0.0.

This issue has been resolved in twine version 5.1.1, as detailed here:
pypa/twine#1124.
