Pushing towards docker templates as a default

[disconsented]

We get numerous questions in the discord about what boils down to i have an issue with dependencies how fix.

One possible way of dealing with this, and the point of this issue, is that pushing towards using the docker environment would largely eliminate these concerns.

We'll also want to expand https://github.com/PufferPanel/documentation/blob/2.x/source/docker.rst to be a full installation guide to help facilitate this.

At the same time, the existing docker installation guide, should be pushed into the background to discourage its use.

Thoughts?
