these changes have no effect with current versions of curl 8 since LIBCURL_VERSION_MINOR would be <34.
For curl version range checks LIBCURL_VERSION_NUM might be a better choice

also, CURL_SSLVERSION_TLSv1_3 is available as of curl 7.52 according to curl documentation
https://curl.se/libcurl/c/CURLOPT_SSLVERSION.html
