Bump selenium-webdriver from 4.0.0 to 4.11.0

Webdrivers doesn't seem to be working with GitHub Actions since Chrome
changed the way to download ChromeDriver [1].

Luckily, webdrivers functionality has recently been added directly to
selenium-webdriver, and version 4.11.0 is compatible with the new way to
download ChromeDriver.

So we're updating selenium-webdriver and removing webdrivers.
