## 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 |

Hello World example
This example shows how to use react context api in our app.
It provides an example of using pages/_app.js to include the context api provider and then shows how both the pages/index.js and pages/about.js can both share the same data using the context api consumer.
We start off by creating two contexts. One that actually never changes (CounterDispatchContext) and one that changes more often (CounterStateContext).
The pages/index.js shows how to, from the home page, increment and decrement the context data by 1 (a hard code value in the context provider itself).
The pages/about.js shows how to pass an increment value from the about page into the context provider itself.
