[IMP] hr_skills: remove optional dropdown

When studio is installed, the List view renderer will always render a
threedot menu to promote studio, but since resume and skill widget
extend that view it also gets rendered on top of the add button.

This change completely removes the optional dropdown menu from those two
widgets.
