Enforce numpydoc's GL05
This error code was shadowed by another with the same name in `pandas`. The old error code was renamed to `PD01` in https://github.com/pandas-dev/pandas/pull/57767

I think `numpydoc`'s GL05 might also be interesting to enforce

```
    "GL05": 'Tabs found at the start of line "{line_with_tabs}", please use '
    "whitespace only",
```
Thanks @tqa236
