Currently, the Dart Dev Tools are opened in the system's default browser.

Since the Dart Dev Tools only work inside the Chrome browser, the Dart extension should always launch Chrome, even if the system's default browser is not Chrome.

Alternatively, there should be a setting to select the browser to open the Dart Dev Tools. This would be useful if a user has multiple compatible browsers (like Chrome and Chromium) or use extensions to show web pages inside vscode (currently, the only known extension, browser-tab, is not suited to display the Dart Dev Tools).
