  packaging: Update min Python version to 3.11 (#7684)

Python 3.10 receives security fixes only and reaches end of life in
October 2026, before the next release. Per RFC 8, raise the minimum
supported Python version from 3.10 to 3.11.

Update the version in REQUIREMENTS.md, pyproject.toml (requires-python,
Black, Pylint, Pyright, and isort) and CI (pytest matrix and
MIN_PYTHON_VERSION).

Update places in code which add code for the older version:

- utils/mkdocs.py: datetime.fromisoformat parses the Z suffix used by
  recent Git natively since 3.11, so the fallback is no longer needed.
- Use the datetime.UTC alias added in 3.11. Ruff enables this check
  (UP017) once it infers the higher target version from requires-python.
- Drop the toml extra for bandit. It provided a TOML parser for reading
  the bandit configuration from pyproject.toml, which the standard
  library covers since 3.11 with tomllib. Here the deciding version is
  the one the workflow runs, which is well past 3.11 already.
