Deployer -> Deployers

[paigerube14]

Arcaflow scenarios of deployer to deployers

Still need to test

Using documentation updates from here

[jaredoconnell]

deployer isn't just replaced with deployers. You also need to add the deployer type. In the case of Kubernetes, that's image. So it should be something like:

deployers:
  image:
    connection: {}
    type: kubernetes

[jaredoconnell]

I missed one other thing. We made type less ambiguous by renaming it to deployer_name. This was a one-time change. I don't expect major renames in the near future.

Untested, but all changes look good.
