Problem

VSCode for Education today uses the view container to host a tree view that is used for navigation by the user through the course.

According to accessibility guidelines, we need to provide a nav role to the container containing the TreeView

As a result, the lack of navigation landmarks hinders users who rely on screen readers from understanding the page structure and efficiently navigating the interface.

Steps to Reproduce:

1. Visit https://vscodeedu.com/.
2. Sign in with a Microsoft account.
3. Navigate to the "Courses" tab, select a course, and select "Start."
4. Enable the Landmarks toggle in Accessibility Insights for Web.
5. Observe that a Navigation landmark is missing from the TreeView area.

Request

Have the ability to specify a role for a view container support landmarks (like nav, search, etc)
