Bug 1991970 - Add a few spare prefs to RecommendedPreferences.sys.mjs to disable features in automation - r=webdriver-reviewers,whimboo
I was poking around browser automation stuff further up the stack and
noticed a few prefs that look like they fit here. Should help keep rarer
browser UI elements stay out of the way and keep PBmode tests
consistent.
