cd2nroff: stricter checks for asterisks for italics

Browse source 
The nroff (man page) version of the markdown docs could get asterisks
mistreated as emphasis - seen in the CURLOPT_WRITEDATA manpage. The
regex now more stricter requires a word character to follow an italics
starting asterisk and there needs to be a word character or a closing
parenthesis before the italics ending asterisk.

Also: fix CURLINFO_CERTINFO.md which used wrong italics - it was not
rendered correctly on GitHub and with other generic markdown parsers.

Fixes #22257
Closes #22260
