* Fix CURL tests by removing deprecated curl_close() calls

    Remove all curl_close() function calls from async extension CURL tests
    to eliminate deprecation warnings that were causing test failures.

    Since PHP 8.0, curl_close() has no effect as cURL resources are
    automatically freed when they go out of scope. In PHP 8.5, this
    function is marked as deprecated and outputs warnings.

    Changes:
    - Removed curl_close() calls from all 10 CURL test files in ext/async/tests/curl/
    - Tests now pass without deprecation warnings
    - Maintains compatibility with modern PHP versions
