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
