MIssing Tabs on component pages
From slack discussion (internal).
We are missing the 'Design' and 'Vue Component' tabs from Component pages:
Possibly related to Vue 2.6 upgrade in gitlab-ui, as we now have both 2.5 and 2.6. And our current BootstrapVue only supports 2.5 (I think). We need Bootstrap Vue RC12 for Vue 2.6 support
See gitlab-org/gitlab-ui#188 (closed) for RC12+ upgrade
