pylint: add failing test when ambiguous abbreviated parameters are set in a config file

This is confusing behaviour. The output is:

```
usage: pylint [options]
pylint: error: ambiguous option: --no could match --notes, --notes-rgx, --no-docstring-rgx
```

The exit code is 2 which doesn't match the documentation: https://pylint.pycqa.org/en/latest/user_guide/usage/run.html#exit-codes
