Update BrowserStack configuration automatically from BrowserStack

[wheatley]

Update BrowserStack configuration from the support matrix from BrowserStacks

Following code updates the configurations that will will be used by

TASK_ID = (ENV['TASK_ID'] || 0).to_i print_info ENV['CONFIG_FILE'] CONFIG_FILE = ENV['CONFIG_FILE'] || 'windows/win10/win10_chrome_81.config.yml' CONFIG = YAML.safe_load(File.read("./spec/support/browserstack/#{CONFIG_FILE}")) CONFIG['user'] = ENV['BROWSERSTACK_USERNAME'] || '' CONFIG['key'] = ENV['BROWSERSTACK_ACCESS_KEY'] || ''

This needs to be improved and updated based on the current browser stacks supporting capabilities
