docs[patch]: fix ipynb links (#14325)

Keeping it simple for now.

Still iterating on our docs build in pursuit of making everything mdxv2
compatible for docusaurus 3, and the fewer custom scripts we're reliant
on through that, the less likely the docs will break again.

Other things to consider in future:

Quarto rewriting in ipynbs:
https://quarto.org/docs/extensions/nbfilter.html (but this won't do
md/mdx files)

Docusaurus plugins for rewriting these paths
