* Update information on pep257 & numpy conventions

The file `error_codes.rst` had information that specified the pep257
default convention, but lacked information about the numpy convention.
I updated this section of the docs with the conventions specified at
the end of `src/pydocstyle/violations.py`, which presently are:

conventions = AttrDict({
    'pep257': all_errors - {'D203', 'D212', 'D213', 'D214', 'D215', 'D404',
                            'D405', 'D406', 'D407', 'D408', 'D409', 'D410',
                            'D411'},
    'numpy': all_errors - {'D107', 'D203', 'D212', 'D213', 'D402', 'D413'}
})
