🌱 Move applier to use Bundle interface

[perdasilva]

Description

Box the boxcutter, configuration, and helm efforts will require an architecture that allows for multiple bundle formats. This PR starts us on that path by creating the simplest Bundle interface:

type Bundle interface {
  FS() fs.FS
}

and updating the Applier to use it. We will want to also update the Resolver and the ImagePuller to use the Bundle interface / API.
