Revert: Abilities API core/get-settings ability.

This reverts [61600]. Other core abilities did not made into 7.0 beta 1 timeline, so adding just a single ability does not adds much value and we are temporarily reverting this addition.
This commit is just a clean execution of the revert command.

Props jorgefilipecosta, jason_the_adams, justlevine.
See #64455.
