`no-redundant-roles` does not detect nullish attributes

[ouuan]

For example, I have an <a> tag that is sometimes disabled:

<a
  :href="disabled ? undefined : 'https://example.com'"
  :aria-disabled="disabled"
  role="link"
>
  maybe disabled
</a>

The w3c specification requires a role="link" when it the link is disabled: https://www.w3.org/TR/html-aria/#example-communicate-a-disabled-link-with-aria

But now this plugin does not know that the href is sometimes not set and reports an error for no-redundant-roles.

I'm not familiar with ESLint plugin development, but I'm wondering if this can be fixed by using type information and checking whether the attribute type can be nullish. Alternatively, maybe there can be an option to treat all v-bind attributes as possibly not satisfying the aria constraint, which does not rely on typing information.
