[ruff] Implement incorrectly-parenthesized-tuple-in-subscript (RUF031) (#12480)

Implements the new fixable lint rule `RUF031` which checks for the use or omission of parentheses around tuples in subscripts, depending on the setting `lint.ruff.parenthesize-tuple-in-getitem`. By default, the use of parentheses is considered a violation.
