Remove option to add title attributes to links in TinyMCE

Hi,

According to our UX designer the "title" attribute is bad for accessibility on links.
Here's more information about titles and accessibility: https://a11yproject.com/posts/title-attributes/

The title attribute can be added when inserting a link in TinyMCE.

We would like to remove this option to make it easiser for web editors to add accessible html.
I hope this makes sense.

Thank you
