feat(aria-roledescription): deprecate and disable rule

[straker]

After testing, the aria-roledescription attribute seems to be fully supported* in the various browsers / screen readers. We can remove this rule now, so will do so in the next major release.

Closes: #3649

• There are a few inconsistencies between browsers, but not enough to keep the rule.

@straker Is another axe rule already testing for valid usage of aria-roledescription? aria-allowed-attr maybe?

[straker]

@kensgists We currently do not have another rule that tests if aria-roledescription is used correctly. #3955 is set up to track validating usage of ARIA roledescription and braille attrs.

@straker Appreciate the information. Will track the progress of that.
