feat(aria-prohibited-attr): add support fallback role

[takenspc]

This PR adds fallback role support to aria-prohibited-attr. For example, <div role="foo img" aria-label="..."> is legal.

At this time, I do not plan to add fallback roles support for other checks.

Thanks for the pr. Unfortunately with axe-con quickly approaching we won't be able to look at this any time soon. After axe-con we'll be able to revisit this again.

Thank you for providing the information. I wish you a successful event, as in previous years. Please let me know if you need any changes are necessary.

This looks good. Just a couple small suggestions. @takenspc thank you for putting this together!

Would you mind adding one or two test cases to test/integration/rules/aria-prohibited-attr/aria-prohibited-attr.html and its .json file as well?

Thank you for your review.

I have added a few tests to test/integration/rules/aria-prohibited-attr/aria-prohibited-attr.html in b405042.

Although I need to update this branch to pass CI tests, it may be better to wait until #4354 is merged.
