[PLAN] Usability Testing and Research on the Toolbar

Problem/Motivation

This Plan/Meta issue gathers all of the usability tests and surveys related to the toolbar redesign. It does not expect any code/MR.

As part of #3373303: [PLAN] Administration UX improvements we're proposing a new Toolbar to navigate across Drupal's administrative UI. We did some research in #3364215: Redesign the toolbar to design a static HTML prototype that served as the initial testing ground for the toolbar.

Goal

The purpose of this issue is to inform the community about how we are gathering user insights and feedback to iterate on the navigation toolbar design and development. This issue is a collection of the Usability Tests and Surveys.
