feat: use configuration files (#9140)
This PR adds configurations files to `puppeteer`'s methods for
configuration. Under the hood, `puppeteer` relies on
https://www.npmjs.com/package/cosmiconfig which resolves several formats
of configuration:

- a `puppeteer` property in package.json
- a `.puppeteerrc` file in JSON or YAML format
- a `.puppeteerrc.json`, `.puppeteerrc.yaml`, `.puppeteerrc.yml`,
`.puppeteerrc.js`, or `.puppeteerrc.cjs` file
- a `puppeteer.config.js` or `puppeteer.config.cjs` CommonJS module
exporting an object

Documentation will be added later.

Fixed: #9128

# PuppeteerNode.launch() method
Launches a browser instance with given arguments and options when specified.
**Signature:**
```typescript
class PuppeteerNode {
launch(options?: PuppeteerLaunchOptions): Promise<Browser>;
}
```
## Parameters
| Parameter | Type | Description |
| --------- | --------------------------------------------------------------- | ---------------------------------------------------------- |
| options | [PuppeteerLaunchOptions](./puppeteer.puppeteerlaunchoptions.md) | <i>(Optional)</i> Options to configure launching behavior. |
**Returns:**
Promise&lt;[Browser](./puppeteer.browser.md)&gt;
## Remarks
Puppeteer can also be used to control the Chrome browser, but it works best with the version of Chromium it is bundled with. There is no guarantee it will work with any other version. Use `executablePath` option with extreme caution. If Google Chrome (rather than Chromium) is preferred, a [Chrome Canary](https://www.google.com/chrome/browser/canary.html) or [Dev Channel](https://www.chromium.org/getting-involved/dev-channel) build is suggested. In , any mention of Chromium also applies to Chrome. See [this article](https://www.howtogeek.com/202825/what%E2%80%99s-the-difference-between-chromium-and-chrome/) for a description of the differences between Chromium and Chrome. [This article](https://chromium.googlesource.com/chromium/src/+/lkgr/docs/chromium_browser_vs_google_chrome.md) describes some differences for Linux users.
## Example
You can use `ignoreDefaultArgs` to filter out `--mute-audio` from default arguments:
```ts
const browser = await puppeteer.launch({
ignoreDefaultArgs: ['--mute-audio'],
});
```
