[PHP 8.4] Fix: Curl `CURLOPT_BINARYTRANSFER` deprecated

The `CURLOPT_BINARYTRANSFER` PHP constant from the Curl extension was no-op since
PHP 5.1, and is deprecated in PHP 8.4. This removes the constant usage to avoid
the deprecation notice in PHP 8.4 and later.

Because this constant was no-op since PHP 5.1 (circa 2005), this change has no
impact.
