patternfly-react Bug - Table - hoverable example invalid markup and selection not announced on navigation

Describe the problem Followup to #7732

The hoverable selectable Table example throws the following warning in the dev environment:

Warning: validateDOMNesting(...): <output> cannot appear as a child of <tbody>

Additionally, due to the way screen readers navigate tables (by cell rather than by row), the row that is selected only gets announced when a row is selected via a cell. Using Tab to navigate between rows (as the table caption instructs) does announce whether the row is selected, but it only announces the aria-label and not the content of the row.

Some possible alternatives:

Add a hidden input to each row, similar to the implementation seen in Data list selectable rows example. To avoid invalid markup, I believe this might require having an empty column similar to the table examples that use visible radio inputs.
Add a hidden input to the first cell of a row, and add styling so that when the radio input has focus it looks like the row has focus.
Move the current output element to the first <td> element of a row

How do you reproduce the problem? Navigate the Hoverable selectable table example with a screen reader

Expected behavior Markup is valid, and users can be notified whether the current row is selected as best as possible
