Severity: wishlist

The attached patch make `Info-goto-node-web' copy the URL as kill with a
prefix argument, instead of opening it with `browse-url'.  I've seen
this feature requested a couple of times now by various people.

Since `Info-goto-node-web' is new in Emacs 29, this could perhaps be
considered safe enough for emacs-29, but master is also fine, of course.
