doc: Change documentation for =0 for non-boolean options

PR #12713 changed the interpretation for negation of non-boolean options
(e.g. -noconnect) to no longer set the option to 0, but to remove it
from the options.

I think this is better because it gets rid of the special meaning of
'0'.

However it needs to be documented. I attempt to do so in this PR.
Addreses #14064.
