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.
Note we now have to use the `Options` class instead of the
`Capabilities`. We're updating Capybara since its changelog mentions its
latest version also adapts these changes in Selenium.
