### What?
Fix the `cms-contentful` example to use the async APIs introduced in
Next.js 15:
- Await `draftMode()` in `app/page.tsx`, `app/posts/[slug]/page.tsx`,
and
`app/api/disable-draft/route.ts`
- Update `params` type to `Promise<{ slug: string }>` and await it in
`app/posts/[slug]/page.tsx`
### Why?
In Next.js 15, `draftMode()` from `next/headers` became async and must
be awaited.
Page `params` are also now typed as a `Promise`. The example was using
the old
synchronous patterns, causing the build to fail and the app to not work
when running against the latest
version of Next.js -- this example project uses latest version of
next.js in the package.json.
### How?
Awaited `draftMode()` at each call site and updated the `params` type
signature to
`Promise<{ slug: string }>` with a corresponding `await`.

## 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!
