bug#51236: 27.2/28 small typos/faq correction?

[Ian Nehera]

Hi, I found a couple small typos in 27.2 that are still present in the source 
for 28.1.

doc/lispref/searching.texi line 2174: missing ’s’ on "describe"
        - Because the match data normally describe[s] …

url-retrieve-synchronously doc-string

                - Change V1: there [is] no data ...
                - Change V2: or nil if [the buffer contains] no data […] (the …

The other thing I found is that the Emacs FAQ.

doc/misc/efaq.texi line 1905:
Yanking text in isearch recommends ‘M-y’ for yanking text out of the kill
ring. This works, but the cross referenced manual page only mentions
the usual ‘C-y’ method with ‘M-y’ yanking previous kills. Is the manual 
out of date or should the FAQ be updated?

Thanks,
Ian
