Enable "Ejection"

This action is focused on users who don't want to know much about the details of how their application is deployed, which is great! But this does present a potential issue down the road for some projects as they mature. Users may find themselves outgrowing the opinionated "black box" approach that this action provides.

I think a possible solution is to provide a guide or perhaps even a feature that helps transition to a more flexible and managed approach. I like to think of this as "Ejecting" the plugin, which is terminology borrowed from [Create React App](https://create-react-app.dev/docs/available-scripts/#npm-run-eject).

At minimum, a guide explaining how to transition to managing your own TF stacks by hand would be great. But In an ideal world, a feature could be implemented to help by opening a PR to scaffold the pieces necessary for such a transition.
