Raised in response to this

Instead of always linking to latest, link to the versioned documentation where the version of the built software is known

For reference, this was versioned before as well -- each release branch changes the tail of its root.
See also #12446, #12462, #12473.

That's why I changed the title to say "dynamically get", as before it was statically referenced. The dynamic variant is more resilient to change, so I think that's a good change.

The scope is also for the CLI in this case; per the above PRs, there are still several other places that use static version links that could be updated to use this dynamic variant instead.
Some won't be updatable as they're in static documentation (e.g. example YAML, swagger, direct README and other direct markdown (vs docs website rendered), etc). UI would also need similar code to pull out the version numbers to make its references dynamic

Yeah, this is this story: I forgot this existed at all when writing #13265, despite me having used it before in #11646 - so #13265 wasn't using this, and I wrote this function and pulled it out into this PR.

Anyway, I think we're in agreement this is a good change, so I'll fix up some of it in #13265.
