py(deps[dev]): Add sphinx-autodoc-api-style and bump gp-sphinx stack to 0.0.1a5

why: Wire in the standalone api-style package next to gp-sphinx; align dev/docs
pins and the lockfile with the latest gp-sphinx workspace releases.

what:
- Add sphinx-autodoc-api-style to dev and docs groups
- Add uv.sources path overrides for gp-sphinx, sphinx-autodoc-api-style,
  and sphinx-autodoc-pytest-fixtures
- Pin gp-sphinx, sphinx-autodoc-api-style, and sphinx-autodoc-pytest-fixtures
  to 0.0.1a5; regenerate uv.lock
