Docs: No API Docs for git.config.GitConfigParser

The [API docs](https://gitpython.readthedocs.io/en/latest/reference.html) are great and detailed. However, the class `git.config.GitConfigParser` is only mentioned by name:

The link "Alias of `GitConfigParser" refers to the line above.

It would be great if methods like `get_value(...)` would be documented.
