docs(misc): set up redirect rules for recipes and fix broken nx-api redirects (#31426)

The Algolia sitemap notified on some 404s, so this PR addresses those
that were either not handled or handled improperly.

Two fixes:
- Add missing redirects for `/recipes` that have changed
- Update `/nx-api` redirects to account for sub-paths like
`/tecnologies/react/next`

The crawler results for 404 is at:
https://dashboard.algolia.com/apps/PCTGM1JTQL/crawler/crawler/867fee54-cdee-47cc-893d-297cb8edb0ff/monitoring/list?status=SKIPPED&reason=http_not_found&readable=HTTP%20Not%20Found%20%28404%29

Finding the redirects and validating them on canary.nx.dev were both
done with AI assistance. The verification script is attached here:
