bug#69312: 30.0.50; [WISHLIST] dicitionary buffer should retain search information

[Juri Linkov]

> Currently when searching with dictionary.el, the query is
> messaged.
> e.g. in dictionary-do-search:
>
> ```emacs-lisp
> (message "Searching for %s in %s" word dictionary)
> ```
>
> It would be better to display this information in the resultant
> buffer somehow (inline, via the header-line, etc).
> Especially for the case of `dictionary-match-words`, which matches
> against a PATTERN argument.
> I'd like to not have to remember what my query was if I come back
> to that buffer at a later time.
