DAR103 on built in types and modules parameters with backticks (``) surrounding them

[justbispo]

Summary

When using backticks (``) on parameter type for built in type parameters (str, int, list...) and modules (os, re...), the DAR103 error is shown.
This doesn't happen with module classes (os.DirEntry, re.Match...).

Is this working as expected? Or is this a bug?

Reproduction

1. Create a demo.py file with the following content

async def foo(
    param1: os.DirEntry,  # any random class
    param2: str,
) -> None:
    """
    Description here

    Parameters
    ----------
    param1 : `os.DirEntry`
        param1 description.
    param2 : `str`
        param2 description.
    """

2. Execute darglint -s numpy demo.py

Expected result

No errors reported by darglint or errors reported in both parameters.

Actual result

This error is shown by darlint:

demo.py:foo:9: DAR103:  ~param2: expected str but was `str`
