[Github repo enhancement] Automatic preview of campfire

[datryn-ribdun]

Describe the feature you'd like
Upon creation of a PR, some infra (github actions, circle CI, jenkins, etc) should create two fake ships (~zod and ~bus), install the campfire desks, install the frontend, then provide links to the two instances (ship1.myships.com/apps/campfire/, ship2.myships.com/apps/campfire/).

Context
Whenever I make a PR, first thing I do is make two fakezods, install the campfire desk, build the React project, then upload that to the ship via the /docket/upload page. This is error prone, and creates friction if someone wants to contribute to the project.

Breaking this down into:

• CI that builds the javascript, and reports any errors
• CI that creates a urbit ship, then does the install procedure (|merge, |commit, |install)
• CI that does the /docket/upload procedure to get the dist folder of the UI onto the ship.

Other benefit of getting this setup is that our deployment get mostly automated. You could have a release procedure that does the install, except does it on the distribution moon.

I think bouncer can do almost everything I need (except maybe the s3 upload)
