chore: drop duplicate PLR1714 ruff rule

[even-even]

Problem

after https://github.com/pytest-dev/pytest/pull/12622/changes#diff-50c86b7ed8ac2cf95bd48334961bf0530cdc77b5a56f852c5c61b89d735fd711R107 "PLR1714" ruff rule doesn't need. "PLR1714" include in "PLR" ruff rules.

Fix

delete twice "PLR1714"

Tests

Also: after delete PLR1714 pyproject-fmt was formatting lint.extend-select block.

after email exchange i consider this human after all
lets till crop down the description to something actually human - a slightly shorter statement of the problem is enough - pre-commit is tested and visible on ci, fix is self-evident and the cursed 3 part of problem/fix/validation is an ai slop bingo hit

Fair enough
