Description of the bug

Some cases that are not yet implemented cause mkdocs build --strict to fail
See:

To Reproduce

Unfortunately this doesn't reproduce the issue with Alias, but essentially this happens for internal Pydantic type Alias("Foo", __main__.Foo) in a similar case:

from typing import TYPE_CHECKING
from pydantic import BaseModel

if TYPE_CHECKING:
    Foo = str
    """A foo string with validation or something."""
else:
    Foo = str | bytes


class MyModel(BaseModel):
    def func(self, foo: Foo) -> None:
        print(foo)

I'm not sure why Griffe is parsing the func as griffe.Alias in my case, but fundamentally it's a specific case that's not implemented in griffe-pydantic yet, that's not a problem.

Expected behavior

Ideally, I could silence this warning (or this type of warning) in the configuration.
I'm OK with this not being processed since it doesn't break the documentation.

I also can't see a way to change the logger level to logging.ERROR through the config.
