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($ch) call (and its //close connection comment) from ReCaptcha::check(). Since PHP 8.0 cURL handles are CurlHandle objects freed automatically at end-of-scope, the call was a no-op and is deprecated in PHP 8.5. The change is correct and has no behavioral impact.

Confidence Score: 5/5

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

Single-line deletion of a function that has been a no-op since PHP 8.0. No logic, data, or security implications. No new issues introduced.

No files require special attention.
