Feature and motivation

Continuation of #11334. Currently, Selenium Manager downloads chromedriver from: https://chromedriver.chromium.org/

To support chromedriver canary, it should also be able to download artifacts from: https://chromedriver.chromium.org/chromedriver-canary

Usage example

./selenium-manager --browser chrome --browser-version canary

... and canary exists on the machine, but the required driver version is unavailable in the stable chromedriver repository.
