Dead link to "api" in Reference

[Sporarum]

In https://docs.scala-lang.org/scala3/reference/
The button "API" as the top left does nothing, and if middle-clicked opens a "404 Not Found" page (not a custom 404 page, the browser one)
It links to https://docs.scala-lang.org/scala3/reference/api/index.html
And not to https://www.scala-lang.org/api/3.x/index.html

Probably related to #25151

There should be no API button in reference - it hosts only reference docs with additional links stability guarantees
