webdriver-manager should download Chromium's latest versions released and download the lowest value for ChromeDriver

[cnishina]

This should download the latest stable version that should match up with Chrome. At least that is the assumption

[cnishina]

Should parse for channel for stable.

From there it looks like we could hit:

https://chromedriver.storage.googleapis.com/LATEST_RELEASE_76

Response: 76.0.3809.68

Or LATEST_RELEASE_ major value and get the version number. This would make life easier.

(Note, this might have not existed back when this was first implemented but I'm glad it exists. Also this will allow me to delete extra code. Yay!)

Hrmm.... I have duplicate bugs. Going to keep this one open since it relates to the issue. Previous bug is #280

[IgorSasovets]

Hi, @cnishina ! What if the webdriver-manager hit https://chromedriver.storage.googleapis.com/LATEST_RELEASE to get the latest chromedriver version? I faced with the chromedriver update issue when updated my Chrome browser version to the latest one (78.0.3904.70 at the moment of writing this comment) and protractor refused to start new driver instance because maximum version that webdriver-manager downloads is 76 and it doesn't work with the latest Chrome. Do you have any plan to fix this issue? Please let me know if you need any assistance or help with this. I have been using protractor for years and really like this project.

Sincerely,
Ihor
