Index external tutorials

Potential sources:

• [ ] radio-astro-tools
• [ ] STScI
• [ ] Caltech/IPAC–IRSA
• [ ] CDS-astro
• [ ] Python for Astronomers
• [ ] codeastro
• [ ] DESI
• [ ] Toronto workshop content (Nathaniel), e.g. Coding the Cosmos
• [ ] Workshop tutorials as a book - each workshop is in its own branch, so there’s probably not anything unique in past-astropy-workshops

Implementation:

• do they need to add metadata files for algolia to index them?
• set up repo for indexing external content - see indexjupyterbookpage.py

Some more notes from Astropy Coordination Meeting 2025:

• Suggestion: Mark some tutorials as “user contributed” if they are not vetted by formal sources.
• Reviews will aim to catch redundant and bad practices in contributed notebooks.
