Dan Fandrich 4c1b6f5494 tests: enable more ruff checks
- Checks for missing explicit `return` statements at the end of functions
that can return non-`None` values.
- Checks for classes that inherit from `object`.
- Checks for useless expressions.
- Within an `except*` clause, raise exceptions with `raise ... from err`
or `raise ... from None` to distinguish them from errors in exception
handling
- Checks for variable assignments that immediately precede a `return` of the
assigned variable.
- Checks for `else` statements with a `return` statement in the preceding
`if` block.
- Checks for unnecessary parentheses on raised exceptions.

Closes: #21258
