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.

Greptile Summary

This PR removes the curl_close($this->handle) call from Curl::__destruct() to suppress the PHP 8.5 deprecation warning. Since PHP 8.0, CurlHandle objects are freed by their reference count, so setting $this->handle = null is sufficient and correct. The change is minimal, safe, and does not alter behavior on any supported PHP version.

Confidence Score: 5/5

This PR is safe to merge — it removes a deprecated no-op without changing any observable behavior.

Single-line removal of a deprecated function call that has been a no-op since PHP 8.0. No logic, state management, or API surface is affected.

No files require special attention.
