Add Browserstack API integration and supported browser type

* Created `BrowserstackApi` class for interacting with the Browserstack API, including a method to fetch supported browsers.
* Introduced `SupportedBrowser` type to define the structure of browser data returned from the API.
* Updated `TestRunner` to instantiate and run the test execution process, enabling command line options logging.
