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

Removes the now-deprecated curl_close() calls from all four cURL-based adapters. Since PHP 8.0, CurlHandle objects are cleaned up by object lifetime rather than an explicit close call, and PHP 8.5 will emit deprecation warnings for any remaining curl_close() invocations. The change is correct and consistent across all affected adapters.

Confidence Score: 5/5

Safe to merge — purely removes a no-op deprecated call with no behavioral change.

All four changes are identical one-line deletions of a call that has had no effect since PHP 8.0. No logic is altered, no resources are leaked, and the fix is applied consistently across every affected adapter.

No files require special attention.
