Issue:
Anchor has content question
Hi, I have a anchor tag that is an icon and, because of that, it has no text related to it. I've made some research and it seems we can use `aria-label` in scenarios like that. But, adding `aria-label` to the anchor tag, it still shows the error "vuejs-accessibility/anchor-has-content".

Should this rule consider a valid content, when the tag has aria-label attribute?

Thank you
