[Accessibility][Headings and Labels - User Input]: No Heading level is defined on page.

[ShellySoni]

User Experience:
If headings are not implemented on the page then it would be very difficult for the user to navigate the main content of the page as headings and labels are used to describe sections of content and controls respectively.

Test Environment:
Environment: Chromium Edge (Anaheim) + Narrator
Build Version: 2004 (OS Build 19569.1000)​​
Microsoft Edge Version: 82.0.436.0 (Official build) canary (64-bit)​
Test URL: http://localhost:3000/home

Repro Steps:

1. Open URL: http://localhost:3000/home
2. "Bot Framework Composer" homepage will gets opened.
3. Select any of the previously created bot from "Recent Bots" or create one from the available Bots under 'Examples' and activate it.
4. Activate 'Headings' using accessibility insights for web or activate scan mode and then press 'H' key to look for headings defined on page.
5. Observe the issue.

Actual:
No Heading is defined on page.

Note:
Same issue is repro within :Bot responses, Notifications, and About page.

Expected:
Heading should be defined on page.
