Button - update console error for accessible name and move aria-expanded location

Describe the enhancement or change
Followup to some comments left in https://github.com/patternfly/patternfly-react/pull/11861/

• The console error with the isSettings || isHamburger || isFavorite conditional for the accessible name (line 164 in that PR) should be updated to remove that conditional. We should be throwing an error for any button that doesn't have children, aria-label, or aria-labelledby
• The aria-expanded attribute (line 239) should be moved below the {...props} so that it won't be overridden by a manual aria-expanded being passed in
• Several tests related to the above points will need to be updated in some fashion as well

Is this request originating from a Red Hat product team? If so, which ones and is there any sort of deadline for this enhancement?

Any other information?
