bug#40457: 26.3; A little Help from `list-packages'?

So maybe link from the package-mode *Help* to (emacs) `Package Menu'?
(That's what I first thought Tomas meant.)

For me, it felt weird only before reading *Help* of the package-mode.
After that, it felt quite in accordance with the rest of Emacs behavior.

[But that depends of course on whether a user has already met
the e*x*ecute behavior and without considering inconsistencies
in Emacs behavior when e*x*ecuting on not-marked lines.]

I think with new keystrokes there's a risk to confuse (especially a new user)
even more: for example, using I (uppercase-i) and D per one package
install/delete would make already inconsistent U even more inconsistent.

Maybe also change `package-menu-quick-help' output:
it could be improved by mentioning *marking*, not only the action.
