What does this MR do and why?

Fix the JH E2E test due to the super_sidebar_enabled method to be removed, and adjust the JH E2E tests to fit the super sidebar page.

List:

• refactor go_to_performance_analytics method
• refactor click_access_tokens method
• fix jh/qa/qa/page/group/settings/usage_quotas.rb element
• skip the jh/qa/qa/specs/features/browser_ui/1_manage/login/onboarding_spec.rb test due to the removal of JH onboarding process.
• skip the jh/qa/qa/specs/features/browser_ui/2_plan/pages test due to the difference in the location of the Pages page compared to Upstream.
