Fix chromedriver on CI
Some observations:
- it seems chromedriver still needs Chrome to be installed, so we can't just use an image like
ruby:2.4
-
chromedriver-helper
is still needed for local test runs, and actually overrides the chromedriver version included in the Docker image - the actual problem was that the lastest chromedriver version 2.37 only works with Chrome 64-66, but we have version 63 in the Docker image. This was fixed by adding
chromedriver-update 2.36
