Bug - Button - revert aria-disabled logic

[thatblindgeye]

Describe the problem
#11478 introduced possible breaking change so we should revert for now and wait for the next breaking change release to make the updates.

Since the 6.2 release has gone out I'm going to close this. If we hear anything from consumers we can revisit whether we need to revert this logic.
