Ensure chromedriver version matches browser version

Fixes #172.

There was an issue with using `driver_version="browser"` in undetected
Chrome mode in SeleniumBase 4.20.0. SeleniumBase 4.20.1 fixes that.
Additionally, the Docker image no longer needs to explicitly download
the Chromedriver (there is no option to do `sbase get chromedriver
browser` yet). Instead, it will download the driver the first time
SeleniumBase initializes the driver.

 ### Upgrading
 - Upgrade the dependencies to the latest versions by running `pip install -r requirements.txt`
 - If you are using Python 3.7, the script still works. However, it is officially unsupported and therefore recommended to upgrade
