## 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 [Prismic](https://prismic.io/) CMS example
(`examples/cms-prismic`) to use the latest Prismic libraries, tools, and
conventions.
- Uses `npx @slicemachine/init` to bootstrap new Prismic accounts and
content repositories.
- Uses [Slice
Machine](https://prismic.io/docs/technologies/slice-machine) to model
content.
- Uses [Slices](https://prismic.io/docs/technologies/slice) to write
post content.
- Uses the latest versions of the following packages:
- `@prismicio/client`
- `@prismicio/helpers`
- `@prismicio/react`
- `@prismicio/next`
- Adds generated TypeScript types for Prismic content. The example
remains as a JavaScript codebase (i.e. not TypeScript), but makes use of
the types via JSDoc.
