doc: omit regex duplication from man page
Inspired by a bug report by Borden (bug#81341).
* doc/grep.in.1: Do not attempt to document BREs and EREs in
detail, as that’s the job of regexp(7), just as documenting PCREs
is the job of pcre2pattern(3).  Just document GNU extensions.
This helps avoid duplication in the manual that complicates the
reader’s job and increases maintenance effort.  Come to think of
it, pcre2pattern(3) is the only PCRE man page we need to cite, so
do that too.
