Summary

• Upgrade the container runtime from PHP 8.4 to PHP 8.5 on Alpine.
• Update PHP package names and PHP-FPM binary/config paths to the PHP 8.5 equivalents.
• Update related documentation/examples to reference PHP 8.5.

Why

• Keep the image aligned with the current PHP minor release for ongoing compatibility, security fixes, and maintenance.

Notes

• On PHP 8.5, OPcache is now built-in and no longer optional (PHP8.5 Changelog), so it does not require a separate php85-opcache package anymore.
