Moodle 4.2+ requires 64-bit PHP (IIAB should likely enforce 64-bit CPU &/or 64-bit OS &/or 64-bit kernel here?)

[holta]

Example Moodle 4.2.2 install attempt on "32-bit" (armhf) RasPiOS 12 even when running a 64-bit (aarch64) kernel:

TASK [moodle : Execute /opt/iiab/moodle/moodle_installer IF /opt/iiab/moodle/config.php doesn't yet exist -- REQUIRES 'max_input_vars = 5000' (or higher) in /etc/php/8.2/cli/php.ini IF PHP 8+ (as set up by www_options/tasks/main.yml) -- WHEREAS LATER ON Moodle uses /etc/php/8.2/fpm/php.ini during regular operation] ***
