[DFCT0010082] Fix inconsistent menu highlighting

[ChrisHuynh333]

What does this PR do and why?

This PR fixes the sidebar menu highlighting to be more consistent, as well as incorporate menu highlighting in newer dropdown menus.

The fixes include:

• Adds sidebar highlighting for user workflow executions index and show pages
• In projects and groups, if an item on the sidebar is selected under the settings dropdown, the settings dropdown will now stay in the 'open' state and the associated selection will remain highlighted
• Converted many def current_page calls in controllers to now use translations rather than the previous hardcoding as this would eventually cause issues once the application uses localization, as the sidebar selection/highlighting was dependent on these hardcoded out strings being equal to the sidebar translation. Ie: Members in French will probably not == 'members'

How to set up and validate locally

1. Navigate to projects and groups, select each item under Settings and ensure Settings remains open and the associated selection is highlighted
2. Navigate to the user workflow executions index and show pages, and ensure Workflow Executions on the sidebar remains highlighted
3. Because much of the def current_page calls through the codebase has been changed, click through the website and ensure the associated selections are highlighted on the sidebar
