Move websocket dependency to selenium-devtools gem

Even though Selenium::WebDriver::DevTools actively uses WebSocket gem,
it cannot be loaded and work without first requiring selenium-devtools
gem. However, if the user doesn't intend to use
Selenium::WebDriver::DevTools, there is no need for them to even install
websocket gem. Hence, it makes sense to actually move this dependency
into selenium-devtools gem.
