## 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)

### What?
This PR adds the `cms-sitecore-xmcloud` example.
Sitecore XM Cloud is a headless CMS platform that empowers content editors to manage content, layout, and structural aspects of web pages. The Sitecore JSS framework connects frontend JavaScript applications to the XM Cloud API, allowing retrieval of content and presentation layout information.
Sitecore JSS for Next.js integrates Next.js with Sitecore JSS, offering a structured approach to connect a Next.js application to XM Cloud. The `cms-sitecore-xmcloud` example, derived from the Sitecore JSS initializer, showcases the frontend application exclusively, omitting backend implementation details.
### Why?
While Sitecore offers detailed documentation for creating XM Cloud projects and JSS applications, existing starter templates often combine frontend and backend configurations. The `cms-sitecore-xmcloud` example focuses solely on the frontend application and includes environment variable examples to establish a connection with XM Cloud, eliminating the need for a .NET-compatible machine.
### How?
For comprehensive guidance on setting up an XM Cloud site and JSS application, refer to Sitecore and Vercel documentation. The `cms-sitecore-xmcloud` example is created using the Sitecore JSS initializer, integrating Next.js and SXA (Sitecore Experience Accelerator) add-ons. Further documentation can be found at:
