Extract chromedriver directly to bin folder

What does this MR do and why?

Extract chromedriver directly in to /usr/local/bin folder.

At some point webdriver.zip started to include additional folder so chromedriver was not in PATH anymore after extraction since it wasn't directly in the /usr/local/bin folder. This leads to unnecessary driver download in all CI jobs which tends to fail sometimes.
