1. fix: Don't require redundant role for <img alt="" /> …

   Fixes ember-template-lint#2951
   
   This updates the `require-valid-alt-text` rule so that it does not
   *require* setting `role="presentation"` or `role="none"` for an `<img
   alt="" />`.
   
   Context
   
   After bumping `aria-query` in ember-template-lint#2927,
   `ember-template-lint` began reporting an error for the following:
   
   ```html
   <img alt="" role="presentation" />
   ```
   
   The error is from the `no-redundant-role`. I believe it is correct to
   report an error in this case because `<img alt="" />` already implicitly
   has a `role` of `presentation`.
   
   However, this new behavior was in direct conflict with part of the
   `require-valid-alt-text` rule that required setting
   `role="presentation"` or `role="none"` whenever an image has `alt=""`.
