How to exclude an API member from being processed by numpydoc

Context

I need type annotations and this project doesn't support this yet (#196, #356)- I tested out successfully sphinx.ext.napoleon, but that project doesn't provide a validator (crazy, right?), so here I am, awkwardly in the middle of two lovers.

Feature request

Regardless if during Sphinx build or from the pre-commit hook, I would like to specify a list of API members to ignore.

Numpydoc already provides numpydoc_validation_exclude, but that is indeed for validation, not the whole thing.

In fact what I get if I use the following configuration,

extensions = [
    "numpydoc",
    "sphinx.ext.autodoc",
    "sphinx_automodapi.automodapi",
    "sphinx.ext.napoleon",
]
napoleon_numpy_docstring = True
numpydoc_show_class_members = False
# Report warnings for all validation checks except those specified after "all"
numpydoc_validation_checks = {"all", "ES01", "SA01", "EX01", "RT02"}
# for why we currently ignore "RT02" see https://github.com/numpy/numpydoc/issues/244
numpydoc_validation_exclude = {
    "my_module.greeting",
}

with the following function,

def greeting(name: str) -> str:
    """
    Perform a greeting.

    Parameters
    ----------
    name
        Name to use.

    Returns
    -------
    greeting
        The greeting.
    """
    greeting = "Hello " + name
    return greeting

Is this (see that the Parameters section is doubled)?

Start with the Sphinx build and pre-commit paths described in the issue, comparing their behavior with the existing numpydoc_validation_exclude configuration. Determine how an API-member exclusion list should apply to the shown greeting example; done means the member is skipped during processing in both contexts without changing validation-only exclusions.
