Add "--describe" to CLI

[taylordowns2000]

Add a --describe function to the openfn deploy CLI, which given a configuration, returns a project.yaml and state.yaml for the requested project.

We'll be using this for the "automated commits to github" story so that changes made through the UI in Lightning can be committed to github.

More context

1. you’ve just built an API in lightning that returns a project.yaml. Make it possible to call this API using an API-TOKEN
   • (That may require a PR against Lightning before a PR against Kit.)
2. there’s an existing API in lightning that already returns a .state.json, and it’s already accessible via API-TOKEN
3. once you’re happy with how allow cron #1 and Setup example fails, could not resolve "@openfn/workflow-diagram" #2 work, extend the CLI with a function that, when given a configuration.json and (somehow…) a projectUuid (via cli argument maybe? via config?) overwrites whatever is in the projectPath and statePath with the results of allow cron #1 and Setup example fails, could not resolve "@openfn/workflow-diagram" #2 from Ligthning.

Another way to think of it

1. this is being used by a local developer to DISCOVER changes to a remote project.
2. Imagine you’re in a git repo.
3. You run openfn deploy --describe .c config.json
4. You run git diff
5. You see how the project has been changed remotely and decide whether or not to commit or discard those changes to your repo.
