Add PUID and GUID variables to Docker container

[yacob841]

I currently have been using let’s say 104:105 as my PUID and GUID for Kaizoku and Komga. Tranga 90% of the time is using root:root, not sure why/how but there has been 2 times where it’s set it to 104:105. (This has been causing my Komga to not be able to view any books downloaded by Tranga) I've tried using the "user" field in docker-compose but that causes issues with internal permission denied errors

You are creating the container as root which is why all files are created with that user.
The current workaround is to create the container as 104:105 .
