Ability to silence warnings (e.g. "Param does not appear in signature") about griffe

[pawamoy]

I assume Pydantic support isn't something that will be worked on (likely living in an extension to Griffe or something?), which is fine.

Actually I just released an experimental extension for Pydantic 😄 https://mkdocstrings.github.io/griffe-pydantic/

We do have a warn_unknown_params docstring option but it's not properly passed to the right functions. I'll fix this asap.

Here is how to use it:

# mkdocs.yml
plugins:
- mkdocstrings:
    handlers:
      python:
        options:
          docstring_options:
            warn_unknown_params: false

(won't have any effect until fixed)

It's now fixed, you should be able to use warn_unknown_params: false to disable these warnings 🙂
