docs(feat[api-style]): Enable API badge styling from gp-sphinx

why: The new gp_sphinx.api_style extension adds type and modifier
badges to autodoc entries, matching the visual language of
sphinx-autodoc-pytest-fixtures.

what:
- Add gp_sphinx.api_style to extra_extensions in docs/conf.py
- Point gp-sphinx and sphinx-autodoc-pytest-fixtures to api-styling branch
- Relax version pins from ==0.0.1a1 to >=0.0.1a1
