ui: Drop the temporary fix for missing popper.js 2.0

- Latest version of libjs-bootstrap5 depends on
node-popper2. However, version in Debian bookworm still continue to have
incorrect dependency. So, add explicit dependency on node-popper2 until we stop
supporting Bookworm.

Tests:

- In stable and testing VMs, install node-popper2 and notices that the following
work as expected:
  - User menu dropdown in desktop and mobile layouts.
  - Help menu dropdown in desktop and mobile layouts.
  - Notification dropdown.
  - App extra actions dropdown.
