[ty] Add tests for dataclass fields annotated with `Final` ( #19202 )
...
## Summary
Adds some tests for dataclass fields that are annotated with `Final`
(see comment
[here](https://github.com/astral-sh/ruff/pull/15768#issuecomment-3044737645 )).
Turns out that nothing is needed here, everything already works as
expected (apart from the fact that we can assign to `Final` fields,
which is tracked in https://github.com/astral-sh/ty/issues/158
