## Description
This PR ensures that the default prettier config is used for examples
and templates.
This config is compatible with `prettier@3` as well (upgrading prettier
is bigger change that can be a future PR).
## Changes
- Updated `.prettierrc.json` in root with `"trailingComma": "es5"` (will
be needed upgrading to prettier@3)
- Added `examples/.prettierrc.json` with default config (this will
change every example)
- Added `packages/create-next-app/templates/.prettierrc.json` with
default config (this will change every template)

This PR updates the `cms-contentful` example to use:
- App Router
- TypeScript
- Draft Mode (previously Preview Mode)
- ISR / Data Cache (revalidations through `revalidateTag`)
Further, it combines many separate files into more manageable single files, and tries to better bucket provider-specific logic into the `lib/` folder. I'm hoping this can be the foundation for re-writing the rest of the `cms-*` examples to use App Router.
Overall, the code is much easier to reason about IMO. Pretty happy with the change. I sprinkled some `any`'s throughout here, but if someone wants to make it better, go for it!
