🚀 preview deployed successfully to Fermyon Cloud and available at https://spin-docs-pr-28-zjhltipy.fermyon.app

At least some of those broken links come from changes being made to the JS SDK links.

# Original site - correct
https://spinframework.github.io/spin-js-sdk/stable/interfaces/Llm.EmbeddingResult.html
# Now - broken
https://fermyon.github.io/spin-js-sdk/interfaces/Llm.EmbeddingResult.html

The old fermyon.github.io doesn't redirect, and the stable is required.

Eek, when was the spin-docs site forked/copied? Those got updated on the original site in mid-February (https://github.com/fermyon/developer/pull/1477/files). Are we working off a 6-week old version of the docs? Older?

ETA: Yes we are. Recent changes are just missing from this version of the site. Looking to see how far back we need to go.

[itowlson]

Okay I think we have up to Feb 14. We need to reapply:

• Bump elliptic from 6.6.0 to 6.6.1 fermyon/developer#1476
• update js sdk doc links fermyon/developer#1477
• Document spin up --listen fermyon/developer#1478
• fix broken link fermyon/developer#1479
• Remove broken link to swift package manager fermyon/developer#1482
• Scheme doesn't matter for local service chaining fermyon/developer#1483

ETA: also

• fix(install): update install script to support more OS types fermyon/developer#1244

I'm working my way through the backports (for avoidance of duplicate effort!)

[vdice]

Phew, thanks for corraling all of the backports we need @itowlson.

I see a few more broken links to trim down, asides from the otherwise known (#24 and #12); PR soon.

Oops, 1f8ee63 was meant to land in #38 but I forgot to save my open VS Code tab. Sneaking it into this PR.

Possible spurious file? Otherwise LGTM
