What does this MR do and why?

This MR addresses the issue where the disabled "Edit policy" button inside the Drawer component of the Policies page displays a tooltip component instead of the required popover component when hovered over. According to design guidelines, when there is a link in the text, a popover should be used instead of a tooltip. This MR replaces the tooltip component with a popover component to adhere to these guidelines.

How to set up and validate locally

1. Setting Up:

   • Ensure you have an inherited policy for a specific project.
   • Navigate to the group containing your targeted project (e.g., http://localhost:3000/flightjs).
   • Go to the group's Policies pages by clicking Secure > Policies on the left sidebar.
   • Create a new policy by clicking the New policy button.
   • Select the Merge request approval policy for simplicity.
   • Fill out the form with arbitrary choices, ensuring the policy scope targets the desired project (all subgroups/projects in this group or specific projects | {YOUR_TARGETED_PROJECT_NAME}).
   • Click Configure with a merge request and merge the resulting merge request.

2. Validation:

   • Navigate to your project (e.g., http://localhost:3000/flightjs/Flight).
   • Go to the project's Policies pages by clicking Secure > Policies.
   • Click on the inherited policy to open the drawer displaying policy information.
   • Hover over the disabled Edit policy button. It should now display a message using the popover component instead of a tooltip.
