The short descriptions describe the data each info retrieves. The info itself does not 'get' the data. This simplifies and shortens the descriptions and make them more consistent. Closes #19406

NAME
CURLINFO_PRIMARY_PORT - last destination port number
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_PRIMARY_PORT, long *portp);
DESCRIPTION
Pass a pointer to a long to receive the destination port of the most recent connection done with this curl handle.
This is the destination port of the actual TCP or UDP connection libcurl used. If a proxy was used for the most recent transfer, this is the port number of the proxy, if no proxy was used it is the port number of the most recently accessed URL.
