TASK: Upgrade to testcafe to version 3.6.2 (#252)

This pull request tested if the end-to-end tests run with the release candidate 4 of version 3.7.0. But sadly, it did not work out. So the PR also upgrades testcafe from version 3.5 to 3.6 and uses the Firefox for the GitHub actions.

When 3.7.0 is released, we can try DevExpress/testcafe#8286 it again.
