Reference to ‘alist’ in Emacs Lisp Manual without previous explanation

[Pankaj Jangid]

I am reading the Emacs Lisp Manual from beginning and
sequencially. Found reference to ‘alist’ in section 2.4.12 Hash Table
Type without any previous explanation.

Either a brief summary should be provided before this, probably near
2.4.6 Cons Cell and List Types or a cross-reference should be added.
