Revert "feat: switch to the Firefox Stable equivalent by default (#6926)" (#6947)
This reverts commit a25b11659be8887b700311180fcd3653aa9e472b.

In a discussion with Dmitry Gozman we decided to revert this and instead
proceed with the following approach:
- rename `//browser_patches/firefox` to `//browser_patches/firefox-beta`
- rename `//browser_patches/firefox-stable` folder to
  `//browser_patches/firefox`

In all of the folders, we will keep the `BUILD_NUMBER` original so that
it doesn't clash on the CDN.

## [Documentation](https://playwright.dev) | [API reference](https://playwright.dev/docs/api/class-playwright/)
Playwright is a Node.js library to automate [Chromium](https://www.chromium.org/Home), [Firefox](https://www.mozilla.org/en-US/firefox/new/) and [WebKit](https://webkit.org/) with a single API. Playwright is built to enable cross-browser web automation that is **ever-green**, **capable**, **reliable** and **fast**.

Headless execution is supported for all the browsers on all platforms. Check out [system requirements](https://playwright.dev/docs/intro/#system-requirements) for details.
## Usage
```
npm i -D playwright
```
This installs Playwright and browser binaries for Chromium, Firefox and WebKit. Once installed, you can `require` Playwright in a Node.js script and automate web browser interactions.
* [Getting started](https://playwright.dev/docs/intro)
* [Installation configuration](https://playwright.dev/docs/installation)
* [API reference](https://playwright.dev/docs/api/class-playwright)
## Capabilities
Playwright is built to automate the broad and growing set of web browser capabilities used by Single Page Apps and Progressive Web Apps.
* Scenarios that span multiple page, domains and iframes
* Auto-wait for elements to be ready before executing actions (like click, fill)
* Intercept network activity for stubbing and mocking network requests
* Emulate mobile devices, geolocation, permissions
* Support for web components via shadow-piercing selectors
* Native input events for mouse and keyboard
* Upload and download files
## Examples
#### Page screenshot
This code snippet navigates to whatsmyuseragent.org in Chromium, Firefox and WebKit, and saves 3 screenshots.
```js
const playwright = require('playwright');
(async () => {
for (const browserType of ['chromium', 'firefox', 'webkit']) {
const browser = await playwright[browserType].launch();
const context = await browser.newContext();
const page = await context.newPage();
await page.goto('http://whatsmyuseragent.org/');
await page.screenshot({ path: `example-${browserType}.png` });
await browser.close();
}
})();
```
#### Mobile and geolocation
This snippet emulates Mobile Safari on a device at a given geolocation, navigates to maps.google.com, performs action and takes a screenshot.
```js
const { webkit, devices } = require('playwright');
const iPhone11 = devices['iPhone 11 Pro'];
(async () => {
const browser = await webkit.launch();
const context = await browser.newContext({
...iPhone11,
locale: 'en-US',
geolocation: { longitude: 12.492507, latitude: 41.889938 },
permissions: ['geolocation']
});
const page = await context.newPage();
await page.goto('https://maps.google.com');
await page.click('text="Your location"');
await page.waitForRequest(/.*preview\/pwa/);
await page.screenshot({ path: 'colosseum-iphone.png' });
await browser.close();
})();
```
#### Evaluate in browser context
This code snippet navigates to example.com in Firefox, and executes a script in the page context.
```js
const { firefox } = require('playwright');
(async () => {
const browser = await firefox.launch();
const context = await browser.newContext();
const page = await context.newPage();
await page.goto('https://www.example.com/');
const dimensions = await page.evaluate(() => {
return {
width: document.documentElement.clientWidth,
height: document.documentElement.clientHeight,
deviceScaleFactor: window.devicePixelRatio
}
});
console.log(dimensions);
await browser.close();
})();
```
#### Intercept network requests
This code snippet sets up request routing for a WebKit page to log all network requests.
```js
const { webkit } = require('playwright');
(async () => {
const browser = await webkit.launch();
const context = await browser.newContext();
const page = await context.newPage();
// Log and continue all network requests
page.route('**', route => {
console.log(route.request().url());
route.continue();
});
await page.goto('http://todomvc.com');
await browser.close();
})();
```
