StevenandGitHub 4466ba436b chore(examples): use default prettier for examples/templates (#60530)
## 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)

## Related

- Fixes #54402
- Closes #54409
