Icons are purely decorative content and should be removed from the accessibility tree to help assistive technologies.
This is done by adding aria-hidden="true"
on icons elements such as <i class="fa fa-hand-peace" aria-hidden="true"></i>
Since the issue is present everywhere in Tuleap codebase, the first step will address only the TLP documentation so that users that do copy/paste of examples already have the aria-hidden
attribute.
