Reenable flake8-bugbear warning B905 when the minimum required Python version is >= 3.10

See https://github.com/googlefonts/ufo2ft/pull/684. The warning moans whenever you use `zip` without `strict=True`, which is probably always what you want.

Start with pull request #684 and the repository's flake8 configuration to see where B905 was disabled and how the minimum Python version is defined. Reenable the warning when the minimum version is at least 3.10, then run the lint checks and confirm the existing zip calls satisfy B905.
