REPL: display Scaladoc

[SethTisue]

Like the :doc command in the Scala 3 REPL. (And, does Ammonite have a version of this?)

Easy form of this improvement: display the URL of the relevant doc.

Harder form: show the actual Scaladoc in the terminal.

(And, does Ammonite have a version of this?)

AFAIK it does not, it does have source() which is suggested also for the use case of viewing docs.

(Source viewing is another handy feature in Ammonite and REPLs in other languages where I've seen it, but I'll take it elsewhere since this issue has a clear and worthy focus on Scaladoc).

Access to the source code is desirable as well. Perhaps it's enough to provide a link to the online Scaladoc, since the online Scaladoc then links to the source.
