Install PHP 8.2 on Debian 10

This version of PHP is actively supported.

Good news! PHP 8.2 is being actively supported through 31 Dec 2024. After that point, it's advisable to upgrade to the latest version, since the PHP team will only offer security-related support until 31 Dec 2026, at which point PHP 8.2 will be considered "end-of-life".
