change(accessibility): Remove double focus on routerLink button

Related to [Accessibilité] - Boutons liens (#502 - closed)

What does this MR do and why?

• app-button should always use (action) for accesibility (removed routerLink + tabindex="none", we should keep them for . Also renamed click)
• Clickable div should all work with keybord (ensure keyup.enter exists)
• radio-options -> Can't go through all options with keyboard
• listitems roles should be embed + tabs shouldn't be listitems
