Add environment var to set `apc.shm_size` php config

[LeSnake04]

When I got the warning that the apc.shm_size is almost full It took me a long time to figure out how to cleanly fix it in docker and where the config PHP is stored.

It feels a bit odd to me that a setting that the docs recommend to change requires me to figure out where the PHP config dir is and add a file to it.

I would suggest adding a PHP_APC_SHM_SIZE environment variable similar to PHP_UPLOAD_LIMIT.

Agreed. I have no idea where the correct php.ini is.

And which file was the right one to edit this option?

I added the line apc.shm_size=128M to the file /etc/php/8.2/cli/conf.d/20-apcu.ini did a systemctl restart php8.2-fpm.service and the warning disappeared. It would have been really nice if there had been a note about this somewhere.
