Bug 1858875 - Workaround to open the ETP settings when the button is not available in the quick action sheet r=ajoltan DONTBUILD

The test is sometimes flaky when the network connection is bad and trackers don't get blocked, so the protection quick settings sheet doesn't have a "Details" section which contains the button for the ETP settings.
Re-ran the test 50 times, all green: https://treeherder.mozilla.org/jobs?repo=try&revision=9f4373ed5f749ee72d64cf4c490d25470a77fa27&selectedTaskRun=AOedklhKSBiM6cwpudB1_w.0
