Broadcast.broadcasted docstring indicates that it is a private function, but documentation treats it otherwise

[brainandforce]

The Julia manual explicitly notes that Base.Broadcast.broadcasted(f, args...) should be implemented when customizing the default behavior of broadcasting, but when the docstring is pulled up with REPL help, it mentions that the symbol is private:

help?> Base.Broadcast.broadcasted
  │ Warning
  │
  │  The following bindings may be internal; they may change or be removed in future
  │  versions:
  │
  │    •  Base.Broadcast.broadcasted

  No documentation found for private symbol.

  Base.Broadcast.broadcasted is a Function.

Same with Broadcast.instantiate.

Xref #51335, although broadcasted probably also wants a docstring.
