Previously, the instructions and process for updating the version of
Chrome ued in tests assumed that there was always going to be a
ChromeDriver version that corresponded to a Chrome version. For example,
if we wanted to use Chrome v87.0.4272.x, we assumed that there was going
to be ChromeDriver v87.0.4272.x. It turns out that this is not always
the case.
This commit updates the instructions and process for updating the Chrome
version to ensure a valid version of ChromeDriver will be used as well.
