This change resolves an issue in container where the user id is not found.
This will create a passwd file with a single line that is for the container user using the uid and gid of the pterodactyl user.
As an added security benefit this would also stop users being able to just use `/bin/bash` as it sets the users terminal to nologin by default and is configurable
example passwd file contents
`container❌999:999::/home/container:/usr/sbin/nologin`
If this does not completely solve the issue in containers then we need to evaluate the image being used to determine what changes need to happen to the image itself to support the timezone.

This change makes the environment handling logic execute independent of the server itself and should make it much easier for people to contribute changes and additional environment handlers down the road without polluting the server object even more.
There is still a lot of work to do on this front to make things easier to work with, and there are some questionable design decisions at play I'm sure.
Welcome to additional modifications and cleanup to make this code easier to reason about and work with.
