/**
 * Launches headless browsers using Playwright pre-configured to work within the Apify platform.
 * The function has the same return value as `browserType.launch()`.
 * See [Playwright documentation](https://playwright.dev/docs/api/class-browsertype) for more details.
 *
 * The `launchPlaywright()` function alters the following Playwright options:
 *
 * - Passes the setting from the `CRAWLEE_HEADLESS` environment variable to the `headless` option,
 *   unless it was already defined by the caller or `CRAWLEE_XVFB` environment variable is set to `1`.
 *   Note that Apify Actor cloud platform automatically sets `CRAWLEE_HEADLESS=1` to all running actors.
 * - Takes the `proxyUrl` option, validates it and adds it to `launchOptions` in a proper format.
 *   The proxy URL must define a port number and have one of the following schemes: `http://`,
 *   `https://`, `socks4://` or `socks5://`.
 *   If the proxy is HTTP (i.e. has the `http://` scheme) and contains username or password,
 *   the `launchPlaywright` functions sets up an anonymous proxy HTTP
 *   to make the proxy work with headless Chrome. For more information, read the
 *   [blog post about proxy-chain library](https://blog.apify.com/how-to-make-headless-chrome-and-puppeteer-use-a-proxy-server-with-authentication-249a21a79212).
 *
 * To use this function, you need to have the [Playwright](https://www.npmjs.com/package/playwright)
 * NPM package installed in your project.
 * When running on the Apify Platform, you can achieve that simply
 * by using the `apify/actor-node-playwright-*` base Docker image for your actor - see
 * [Apify Actor documentation](https://docs.apify.com/actor/build#base-images)
 * for details.
 *
 * @param [launchContext]
 *   Optional settings passed to `browserType.launch()`. In addition to
 *   [Playwright's options](https://playwright.dev/docs/api/class-browsertype?_highlight=launch#browsertypelaunchoptions)
 *   the object may contain our own  {@apilink PlaywrightLaunchContext} that enable additional features.
 * @param [config]
 * @returns
 *   Promise that resolves to Playwright's `Browser` instance.
