Bug - Button - aria-disabled is false when button is disabled

[nicolethoen]

In the Button component In both cases (disabled or enabled) aria-disabled is always false.

From @thatblindgeye: "It probably doesnt do any harm when the button is enabled but we still don’t need it… Since it’s probably been an issue for however long it probably wouldn’t hurt much more if they just wait for us to provide a fix, which we could try to get in for this milestone"

reported during the OCP + PF6 migration

FYI, on Patternfly v5.4 it worked properly. I have some tests reading aria-disabled on a wizard footer and it all passed.
