Unrecognized option "chrome" under "testwork.mink.sessions.chrome_headless".

[fabianobonomini]

I tried to write down my own test for an sylius 1.10 instance.

I renamed the behat.dist.yml file in behat.yml

I executed the command: APP_ENV=test ./vendor/bin/behat

then I get this error
`In ArrayNode.php line 314:

Unrecognized option "chrome" under "testwork.mink.sessions.chrome_headless". Available options are "appium", "browser_stack", "goutte", "sahi", "sauce_labs", "selenium", "selenium2", "symfony", "zombie".`

the beheat.yml in that object looks like this ( I didn't change anything from the dist file )
