World config: Make depends easier to read (#7396)

* Do not always show every depends textfieds

When there are no dependencies, it does not longer show an empty list.

* Adjust the list height to avoid a scrollbar when possible

* change minimum height and no dependencies message

* Do not get depends for modpacks
