add a bash script to the docs that starts a docker container (or maybe a docker image)

[estebanabaroa]

A lot of people have requested a docker image

I think maintaining an image is probably overkill, a bash script that downloads plebbit-cli and starts it in docker is probably enough.

Or maybe for security a simple docker image that downloads plebbit-cli from github and starts it would be better. People might be wary of running a random bash script.

Or maybe both.

I think people trust docker, but they won't necessarily trust a bash script produced by us. I think maintaing a docker image of plebbit-cli is ideal because we print the URL of seedit/plebchan which can be accessed outside docker. If user needs to use plebbit-js they can just plug the RPC url.

I vote for a docker image tbh
