There was a problem hiding this comment.
Makes sense. Some other package managers also use highest. Even our current doc uses highest.
Generally, Cargo prefers the highest version currently available.

What does this PR try to resolve?
Using "latest" is already inaccurate because patches for previous versions can be released. With min-publish-age adding a time dimension, using "latest" becomes a non-starter.
So instead use "highest". We could have used "maximum" but "highest" felt nicer to me for some reason.
This is part of #17009
