Support flexible templates for app init

[shauns]

WHY are these changes introduced?

Fixes an issue where app templates using certain module types cause app init to fail. The issue is due to the app template using module types that aren't defined within the CLI, but more generally due to app init validating/understanding app configuration.

WHAT is this pull request doing?

Instead, we process app config during app instantiation as opaque blobs -- we don't rely on being able to validate them or a particular structure being in place.

In app init the app is loaded twice -- once as a template, and then again as the local copy of the app is linked to the remote version of it.

How to test your changes?

Locally: pnpm shopify app init --path="<where I keep my apps>" --template="https://github.com/Shopify/shopify-app-template-react-router#include-declarative-definition"
