[Usability][Screen reader-Welcome] Nvda is reading twice for check boxes information

[Kumar2608]

Actual Result:
Nvda is reading twice for checkboxes information present in the welcome tab screen
NVDA is reading as “Open in Debug mode Open in Debug mode check box not checked”
1.Open in Debug mode 2. Azure for US Government

Expected Result:
NVDA should narrate the once for checkboxes information
Example: NVDA should read as “Open in Debug mode check box checked \Not checked “

Note: This issue exits throughout the application for all check boxes
Same issue repro for Edit ngrok settings screen
"User settings,Application updates,Data collection" under check boxes NVDA is reading the twice

Same issue repro for below path
Welcome Bot Framework Emulator ->Create new bot configuration ->Live chat dialog

I will be implementing the fix for the sendbox ("Type your message") being read twice on the Web Chat repo. Therefore my fix will not be available to Emulator until Web Chat is bumped, which should be at the same time that #1759 is fixed. For reference I will link the Web Chat PR that contains this fix below.

This was closed on accident when my PR was merged in Web Chat, above. Keeping this open intentionally until Web Chat is bumped on Emulator.

This is addressed in the WebChat dependency via the following PR: microsoft/BotFramework-WebChat#2423. We will take a new version of WebChat in the coming weeks.
