Bump twine from 6.1.0 to 6.2.0

Sourced from twine's changelog.

twine 6.2.0 (2025-09-04)

Features ^^^^^^^^

• Automatically refresh short-lived PyPI token in long running Trusted Publishing uploads.

  In the event that a trusted publishing upload job is taking longer than the validity period of a trusted publishing token (15 minutes at the time of this writing), and we are already 10 minutes into that validity period, we will begin to attempt to replace the token on each subsequent request. ([#1246](https://github.com/pypa/twine/issues/1246) <https://github.com/pypa/twine/issues/1246>_)

Bugfixes ^^^^^^^^

• Fix compatibility kludge for invalid License-File metadata entries emitted by build backends to work also with packaging version 24.0. ([#1217](https://github.com/pypa/twine/issues/1217) <https://github.com/pypa/twine/issues/1217>_)
• Fix a couple of incorrectly rendered error messages. ([#1224](https://github.com/pypa/twine/issues/1224) <https://github.com/pypa/twine/issues/1224>_)
• twine now enforces keyring >= 21.2.0, which was previously implicitly required by API usage. ([#1229](https://github.com/pypa/twine/issues/1229) <https://github.com/pypa/twine/issues/1229>_)
• twine now catches configparser.Error to prevent accidental leaks of secret tokens or passwords to the user's console. ([#1240](https://github.com/pypa/twine/issues/1240) <https://github.com/pypa/twine/issues/1240>_)

Deprecations and Removals ^^^^^^^^^^^^^^^^^^^^^^^^^

• Remove hacks that support --skip-existing for indexes other than PyPI and TestPyPI.

  To date, these hacks continue to accrue and there have been numerous issues with them, not the least of which being that every time we update them, the paid index providers change things to break the compatibility we implement for them. Beyond that, these hacks do not work when text is internationalized in the response from the index provider.

  For a sample of past issues, see:

  • pypa/twine#1251

  • pypa/twine#918

  • pypa/twine#856

  • pypa/twine#693

  • pypa/twine#332 ([#1251](https://github.com/pypa/twine/issues/1251) <https://github.com/pypa/twine/issues/1251>_)
