docs: use container images

[mudler]

As part of #109 we have now container images published by the pipelines.

We want now to be consistent and have documentation explaining how to use the images, and use these in place of having to setup the environment manually (via git clone, pip and running make commands).

A very basic Dockerfile which builds here:

FROM python:3.12 AS base

WORKDIR /app

RUN apt update && \
    apt install -y nodejs npm && \
    npm install -g pm2
    
RUN git clone https://github.com/opentensor/btcli.git

COPY . .

RUN python3 -m venv bittensor && \
    /bin/bash -c "source bittensor/bin/activate && cd /app && pip install -e ."

RUN cd btcli && \
    pip3 install .
