Some HTML elements have redundant ARIA roles

Created by: metamoni

• What were you trying to do? I noticed that the header in the index view has a redundant role property. There are other header elements that have the same issue, as well as a main with a redundant role="main", a nav with role="navigation" and a th that has a role="columnheader".

<header class="main-content__header" role="banner">

While this doesn't cause any technical issues, it's bad practice and it encourages other developers to follow the same pattern.

A list of all implicit roles is available here: ARIA in HTML
