jammy build will break roundcube

[fleek]

jammy will install php8.1-fpm by default whiles the configuration in roundcube still uses php7.4-fpm. Solution is to add ppa source to the script and install php7.4-fpm and php7.4-cli instead of php-fpm and php-cli.

jammy should use Roundcube 1.6.0 instead, better wait for next release which contains many PHP8 compatibility issues fixed.

I am running the container on a raspberry pi4 and have successfully built the image for arm64 after adding the php ppa and changing the packages to the exact php7.4-fpm and php7.4-cli. I will reverse out my temporary fix when the new version comes.
