BLE001: detect contextlib.suppress ?

```python
try:
foo()
except BaseException:
pass
```
is detected as `BLE001`, while the following isn't:

```python
with contextlib.suppress(BaseException):
foo()
```

please consider if that would make sense to detect it.

Start from Ruff's BLE001 rule and compare how the two Python examples are analyzed. Determine whether contextlib.suppress(BaseException) should be reported consistently with the try/except example, then add or update coverage so the intended behavior is explicit.
