Fix doc and doc-strings for minibuffer window related functions (Bug#28978)

These fixes were suggested by Drew Adams.

* src/window.c (Fminibuffer_selected_window): Disambiguate
doc-string.
* doc/lispref/minibuf.texi (Intro to Minibuffers)
(Minibuffer Windows, Recursive Mini, Minibuffer Misc):  Avoid
the term "currently active minibuffer window".  Disambiguate
documentation of `minibuffer-selected-window'.
