nixos/minecraft-server: optimize world generation inside test

Browse source 
Due to how complex minecraft world generation has gotten in recent
years, it now can take several minutes to complete the first generation
of a world seed, even on relatively new and powerful hardware.

We are testing if a minecraft server can run inside of a nix enviroment,
and not so much about stress testing the CI.

Test running before this change:

> (finished: waiting for TCP port 43000, in 118.49 seconds)

Test running with this change:

> (finished: waiting for TCP port 43000, in 27.88 seconds)

Choice of using `level-type` and `generate-structures` was made as they
support almost every version of minecraft. These two also make it
extremely clear what it does, compared to the more complex
`generator-settings` and all its toggles.
