fix: update broken Pydantic v2 and Ariadne documentation links

Pydantic restructured their docs site when releasing v2, moving pages
from /usage/ to /concepts/. The pydantic-extra-types page no longer has
a standalone docs URL, so the link now points to the GitHub repo.
Ariadne removed their FastAPI integration page, so the link now points
to the Ariadne homepage.
