rustls: remove incorrect SSLSUPP_TLS13_CIPHERSUITES flag

The rustls backend advertises SSLSUPP_TLS13_CIPHERSUITES, but
the code does not actually seem to support it (yet?). Removed
the flag and corrected documentation.

Closes #13452

NAME

CURLOPT_PROXY_TLS13_CIPHERS - ciphers suites for proxy TLS 1.3

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_TLS13_CIPHERS,
                          char *list);

DESCRIPTION

Pass a char pointer, pointing to a null-terminated string holding the list of cipher suites to use for the TLS 1.3 connection to a proxy. The list must be syntactically correct, it consists of one or more cipher suite strings separated by colons.

Find more details about cipher lists on this URL:

https://curl.se/docs/ssl-ciphers.html

This option is currently used only when curl is built to use OpenSSL 1.1.1 or later. If you are using a different SSL backend you can try setting TLS 1.3 cipher suites by using the CURLOPT_PROXY_SSL_CIPHER_LIST(3) option.

The application does not have to keep the string around after setting this option.

DEFAULT

NULL, use internal default

EXAMPLE

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode res;
    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
    curl_easy_setopt(curl, CURLOPT_PROXY_TLS13_CIPHERS,
                     "TLS_CHACHA20_POLY1305_SHA256");
    res = curl_easy_perform(curl);
    curl_easy_cleanup(curl);
  }
}

AVAILABILITY

Added in 7.61.0. Available when built with OpenSSL >= 1.1.1.

RETURN VALUE

Returns CURLE_OK if supported, CURLE_NOT_BUILT_IN otherwise.
