upload file size limit

[tomniers]

The php.ini limits the file size for uploading a submission. This is probably critical for uploading workspace, as they often got a size larger then 2mb.
To change the limit you need to adapt post_max_size, upload_max_filesize, memory_limit wherby memory_limit > post_max_size > upload_max_filesize in terms of value. You need to adapt these values in the php.ini of the php version you are using e.g. code /usr/local/etc/php/7.4/php.ini. Further hints here.
So we need to change the php.ini to change the file size limit of the submission files uploaded in OJS. There is no obvious way to change this limit from OJS or is there? Should we place somewhere a hint that the user is aware of this problem and gets to know how to change it?
