Describe the enhancement requested

The godoc format shows docs in a versioned fashion, making the "basic" link reference v0.0.0 from 2018, and godoc doesn't warn you when docs are outdated. Accordingly, for people to find "real" documentation, they have to manually search for the latest docs.

Otherwise, it gives the impression that the package is abandoned / makes devs waste considerable time — e.g., I work with Go professionally and wasted 15 minutes on the 2018 docs until I realized they were wrong.

I have a PR for this (#39750), which is currently tagged as MINOR, but can't as this change will require tweaks to the release process. I'm creating this issue so I can update the .sh script in that PR and move it from a MINOR to regular PR.
