Running with Channel.RELEASE instead of NIGHTLY

[jnachtigall]

Now with Firefox 57 out, how would it be possible to run the examples with firefox.Channel.RELEASE?

I changed https://github.com/mykmelez/headless-examples/blob/master/selenium-screenshot-node-6.js#L9 from

const binary = new firefox.Binary(firefox.Channel.NIGHTLY);

to

const binary = new firefox.Binary(firefox.Channel.RELEASE);

but this starts the Developer Edition. I use Windows 10 and have Release, Developer Edition and NIGHTLY installed. Nightly is my day-to-day browser, Release is hardly used. But now for a project (together with other people and CI) I would like to use Release for testing and now that 57 is out it should be working.

I guess the docs at https://developer.mozilla.org/en-US/docs/Learn/Tools_and_testing/Cross_browser_testing/Your_own_automation_environment#WebDriver_syntax_crash_course should point to RELEASE too instead of NIGHTLY (I can update them, once I got it running or know at least it should be running)
