Workers list on workflow page is misleading

Describe the bug
On a workflow page there is a Workers tab (and we also show a count for it). This seems misleading to me because it implies that it will be a list of workers who are mentioned in the workflow history for the workflow being displayed. The workers list is actually nothing to do with the workflow being displayed.

To Reproduce
Steps to reproduce the behavior:

1. Go to a workflow page
2. Take note of the Workers count and then view the Workers list
3. Read the event history for the workflow
4. See that the Worker count is probably greater than the number of workers mentioned in the workflow history and depending on when the workflow ran and/or when the last worker start/deploy was, the list of workers doesn't line up.

Expected behavior
The Workers list should either be a list of workers mentioned in the history of the displayed workflow, or else be moved to a different navigation area to avoid implying a relationship.
