change: Make failed cross-reference lookup in docstrings clearer

[pushfoo]

Is your change request related to a problem? Please describe.

When I had a typo in a docstring, the output reported the error as in the markdown file rather than the docstring:

WARNING -  mkdocs_autorefs: api/annotations.md: Could not find cross-reference target
           '[package.oop.annotations]'

Describe the solution you'd like

More detailed / accurate error output which includes:

1. The docstring file
2. The item the docstring is on
3. Docstring line number
4. Ideally, accurate file line number

Describe alternatives you've considered

N/A?

Additional context

I have:

1. A package.annotations submodule
2. A docs/api/annotations file using mkdautodocs (# ::: package.annotations)

The typo was in the package/annotations.py file

Thanks for the change request 🙂 It makes a lot of sense, and this is something I've wanted to improve indeed. PR #46 is a first step to make this possible 😄 I'll report progress here 🙂
