Adds link to settings from dependency proxy

What does this MR do and why?

Adds link to settings from dependency proxy

Expectation

• Dependency Proxy will only show button at group level as Dependency Proxy are only available at the group level
• Dependency Proxy setting lives alongside ellipsis button to clear the cache. If the ellipsis button is not visible (because the user does not have right to clear the cache) then the settings button aligns with the right of the screen.
• Settings button should not show for users who are developer or below (and thus cannot see the settings)
• Navigating to the settings from the feature page opens the corresponding section in the settings.
