jsx-a11y/aria-activedescendant-has-tabindex rule is incompatible with w3c wai-aria examples

[KuSh]

Hi,

I'm trying to implement wai-aria compatible components following w3c wai-aria-practices examples and the following rule causes me problems :
https://github.com/evcohen/eslint-plugin-jsx-a11y/blob/7bcea2006f1d79b399e4aaec82e9cbbbe6ef8cc4/src/rules/aria-activedescendant-has-tabindex.js#L46-L49

This rule doesn't validate w3c following example as it uses negative tabIndex

regards,
Nicolas

@KuSh ya, you're totally right. Thank you for bringing this to our attention!

Let's remove the restriction on it being negative.
