Stop flagging `# ty:` annotations as commented-out code

Hi. Most recent ruff 0.15.7 respects the per-file `# type: ignore` annotation, but fails on `# ty: ignore`. Our workaround is to use `# ty: ignore  # noqa: ERA001`, but we are sure this can be improved.

```python
ERA001 Found commented-out code
 --> cratedb_toolkit/io/mongodb/transform-new.py:1:1
  |
1 | # ty: ignore
  | ^^^^^^^^^^^^
```

Thank you!
