## 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)

- Closes#54409
### Reason for making this change
https://yarnpkg.com/getting-started/qa#:~:text=yarn%2Finstall%2Dstate.,your%20workspaces%20all%20over%20again.
In the official documentation of `yarn`, it is stated that `.yarn/install-state.gz` is an optimization file that developer shouldn't ever have to commit. However, currently, when running `create-next-app`, `.yarn/install-state.gz` is being commited.
### Remaining work
I apologize for only modifying one template initially to initiate the discussion first.
If this change is agreed upon, it should be synchronized with other `.gitignore` templates. Would it be possible to follow a similar approach as in https://github.com/vercel/next.js/pull/47241? I would appreciate any assistance in syncing this change.
Strategized with @balazsorban44 to open one larger PR, with changes to individual examples as separate commits.
For each example, I researched how multiple realworld codebases use the featured technology with TypeScript, to thoughtfully convert them by hand - nothing automated whatsoever.

This PR updates the docs and examples for `create-next-app` to include pnpm usage.
The following script was used to update every example README:
```js
const fs = require('fs')
const examples = fs.readdirSync('./examples')
for (let example of examples) {
const filename = `./examples/${example}/README.md`
const markdown = fs.readFileSync(filename, 'utf8')
const regex = new RegExp(`^yarn create next-app --example (.*)$`, 'gm')
const output = markdown.replace(regex, (yarn, group) => {
const pnpm = `pnpm create next-app -- --example ${group}`
return `${yarn}\n# or\n${pnpm}`
})
fs.writeFileSync(filename, output)
}
```
