the generated project should open in a devcontainer

[adrian-herscu]

Current State
DevContainers are not supported -- this has the following implications:

1. Selenium requires installation of desktop browsers
2. Appium requires installation of an emulator
3. On many Linux distros, applications are installed in containers, such as Flatpak, requiring special configuration to allow spawning of browsers/emulators; see should launch browsers on containerized infra like flatpak #245

See also #242, which preceedes this one.

How to make it better

1. the generated project must open at least on a Docker-backed DevContainer
2. the Docker definition must include at least the Chrome/Chromium browser
3. further, it should include an Android Emulator
4. it should also include Selenium Grid + Appium
