Remove deprecated curl_close calls

[ChiragAgg5k]

What does this PR do?

Removes calls to curl_close(). Since PHP 8.0, cURL handles are CurlHandle objects and curl_close() no longer has an effect; handles are released by object lifetime instead. Removing these calls avoids noisy PHP 8.5 deprecation warnings without changing behavior for supported PHP versions.

Test Plan

• Ran php -l on changed PHP files where applicable.
• Confirmed no curl_close(...) calls remain in this repository.
