Accessibility improvement - change the default link dialogue so it can add aria-label value instead of Title

The default link dialogue for many years has let editors add a Title attribute to the link. We've had feedback from a big public sector company we develop and maintain an Episerver site for that they thought this gave them the ability to add further details of the link for users of screen reader software, and so increase the accessibility of their site. This isn't the case - it's been many years since any of the main screen readers read the Title attribute at all unless configured to do so. All the Title attribute really does is give mouse users a hover-over tip, so is no use at all to increase the site's accessibility. Why not replace the Title field with aria-label, to give editors a real chance to boost the accessibility of their sites? This value could give blind/partially-sited users more information about the link, if the editor deemed it necessary.
