Auto fix the `aria-text` when "Avoid ARIA if it can be achieved without"

[vhoyer]

When the error show on the rule is the Avoid ARIA if it can be achieved without, it's pretty straight forward what needs to be done to fix it, right? we only would need to delete aria-hidden and/or any "suspicious" role (presentation/none), and insert a alt="" in place of them :D, what do you think?

Sure! Feel free to open a PR to handle this.
