Don't name integer and string results in API examples (#4198)

Since ejabberd 24.02, mod_http_api does not name any results,
previously integer and strings were named, but other results were not.
And ejabberdctl obviously does not name results either.
Only ejabberd_xmlrpc does.
Consequently, the documentation should not name results in the examples.
