Broken docs links

Looks like a recent git push broke a few documentation links. The examples on first_steps pages don’t seem to open up. Can someone please confirm?
https://docs.bokeh.org/en/latest/docs/first_steps/first_steps_9

See:

That said, those particular links are on the previously published 2.4.3 docs and should work. There has not been any update to previously published versions, that I am aware of (it is a huge hassle, and very very rarely done), so I can only assume they have been broken since they were published.

It looks like the links on the “dev” docs version are working, if you want to use those for now:

First steps — Bokeh 3.0.0rc3 Documentation

Edit: alternatively, the 2.4.2 links are also working:

First steps — Bokeh 2.4.2 Documentation
