PHP 8.5 compatibility: deprecation warnings

[Abdullah-Sarfraz-Ali]

Deprecation notices observed

dependencies shipped inside LoginPress Pro's Social Login add-on. They contain the bulk of the deprecation notices — chiefly implicitly-nullable parameter types (Type $x = null, deprecated since PHP 8.4), plus curl_close(), __wakeup(), $http_response_header, and a (boolean) cast. They still execute on 8.5 but are the main source of noise.

Steps to reproduce

1. Load the library on PHP 8.5
2. [ Do OAuth and verify ]

Expected

No PHP 8.5 deprecation notices when using supported library versions.

Actual

Deprecation noise on PHP 8.5 (still works, but logs are flooded).

Context

Bundled in WordPress plugin LoginPress Pro for social login .
Happy to test a patch or pre-release.
