aria-orientation should be allowed on radiogroup

[jnurthen]

Expectation:
The ARIA spec allows aria-orientation on a radiogroup. aXe should allow this.

Actual:
aXe allows aria-orientation on all other allowed roles except for radiogroup

Motivation:
The ARIA spec allows aria-orientation on radiogroup. aXe should not give the message
ARIA attribute is not allowed: aria-orientation="vertical"
aXe should allow this attribute - while it doesn't often do anything useful on a radiogroup if not supported by a browser/AT combination it being there does no harm.
If aXe decides to not allow this attribute for some reason then the message should be clear about why and it should not state that it is not allowed (because it is allowed)

axe-core version: 3.5.1

Looks like we should allow this because it will not create a barrier even if not supported

[jnurthen]

would a PR be helpful?

[WilcoFiers]

Definitely, go for it. Thanks @jnurthen.

[straker]

@jnurthen any update on this?

[straker]

This should now be fixed in the latest develop of axe-core.
