ci: pin ChromeDriver to a version compatible with docker image's Chrome (#28494)

By default, `webdriver-manager update` will download the latest
ChromeDriver version, which might not be compatible with the Chrome
version included in the [docker image used on CI], causing CI failures.
Previously, we used to pin the ChromeDriver version on CI in
[ngcontainer's Dockerfile][2]. This was accidentally broken in #26691,
while moving from ngcontainer to default CircleCI docker images.

This commit fixes the issue by pinning ChromeDriver to a known
compatible version.
