BLE001 flags `except Exception as e` if re-raised `from None`

[injust]

Summary

This doesn't trigger BLE001:

try:
    pass
except Exception as e:
    raise e

but this does:

try:
    pass
except Exception as e:
    raise e from None

I think this makes sense. It looks like we currently only support raise-from if the target matches the exception name, as in:

try:
    ...
except Exception as e:
    raise ValueError from e

from #11131.
