[Accessibility][Keyboard - Open]: Navigation within table is not performed using up/down arrow keys.

[ShellySoni]

User Experience:
For keyboard users it is difficult to perform the task if any control does not perform its functionality.

Test Environment:
Environment: Chromium Edge (Anaheim) + Narrator
Build Version: 2004 (OS Build 19564.1005)​​
Microsoft Edge Version: 82.0.425.0 (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. Navigate to "Open" button and activate it.
4. 'Select a Bot' dialog gets opened.
5. Navigate within the table using up/down arrow keys and observe the issue.

Actual Result:
Navigation within table is not performed using up/down arrow keys. When user press down arrow key to navigate to next row, then either the table gets refreshed & focus shifts to another control or new page gets opened.

Note:

1. Same issue is repro within: Save >Define conversation objective table.
2. Select 'Notification' from left navigation bar, when focus reach on table 1st column & press down arrow key, the new page gets open, which is incorrect and when user press 'Enter' key on error, then also nothing is happened. (Refer: Attachment: Functional_Notfication_error)
3. Sorting is also not performed.

Expected Result:
Navigation within table is not performed using up/down arrow keys. When user press down arrow key to navigate to next row, focus should land to next row rather than refreshing the table and new page to open.
