A recent change (#2748) combined the different workspace buttons to free up some space. This is a good change, but there was a little collateral damage. I think the "Update" button shouldn't be grouped; if the template is out of date, it should always be top level instead of in the collapsed array. OR "Update" could be the first button with "Start" being in the drop-down.

Definition of Done:
Update call to action should be more prominent.

AC as per below discussion:

• keep Update in button dropdown
• make it the primary CTA when an update is available
• add an 'Outdated' tooltip (similar to the one in the workspaces table) when an update is available
