Add a tooltip to the publish button to explain the user what is needed to publish a collection

The publish button in the collection editor view is disabled due to some conditions, one of them is to not have a price for any of the items in the collection. Although this is the expected behavior, the experience can be a bit confusing, as there's no visual cue to indicate that something needs to be completed before publishing.


To fix this issue, a tooltip can be added to the button whenever it's disabled, indicating what needs to be done to be able to publish a collection.
