[BUG] PHP Fatal error: Uncaught RuntimeException: Unable to create the "cache" directory

Describe the bug
In my docker log I'm getting a:

PHP Fatal error:  Uncaught RuntimeException: Unable to create the "cache" directory (/opt/kimai/var/cache/prod). in /opt/kimai/vendor/symfony/http-kernel/Kernel.php:686\nStack trace:\n#0 /opt/kimai/vendor/symfony/http-kernel/Kernel.php(593): Symfony\\Component\\HttpKernel\\Kernel->buildContainer()\n#1 /opt/kimai/vendor/symfony/http-kernel/Kernel.php(136): Symfony\\Component\\HttpKernel\\Kernel->initializeContainer()\n#2 /opt/kimai/vendor/symfony/http-kernel/Kernel.php(196): Symfony\\Component\\HttpKernel\\Kernel->boot()\n#3 /opt/kimai/public/index.php(32): Symfony\\Component\\HttpKernel\\Kernel->handle()\n#4 {main}\n  thrown in /opt/kimai/vendor/symfony/http-kernel/Kernel.php on line 686

after a docker pull since about 12h ago when accessing my kimai2 instance and the instance was inaccessible.

I think 99dea36#diff-dd2c0eb6ea5cfc6c4bd4eac30934e2d5746747af48fef6da689e85b752f39557R254 could have done this.

I'm only reporting in case someone else has this too.

I couldn't fix this by just setting the permissions for the /opt/kimai/var or /opt/kimai/var/cache manually, they were reset. Not even make them world writable did fix it, I just got a different error 500 (with no further error in docker log, I had to visit the kimai2 logs in the log directory).
I could only fix this by setting the env vars to 33 (www-data), 1000 (www-kimai) didn't work for me:

      - USER_ID=33
      - GROUP_ID=33

All other files/dirs were already owned by www-data.

That's totally right, I didn't think about that. I'll set the defaults to 33

This 9cb5104 should fix it

Thank you! I wonder if using other UIDs/GUIs would even work... 🤔
