Consider making toggleText required for the base dropdown
The following discussion from gitlab-org/gitlab-ui!3218 should be addressed: - [ ] @sdejonge started a [discussion](https://gitlab.com/gitlab-org/gitlab-ui/-/merge_requests/3218#note_1235041911): > **suggestion:** add `toggleText` and `textSrOnly` props to relevant stories to illustrate labelling. Maybe future work can be to have `toggleText` required on base dropdown to enforce labels. > This improvement is important for accessibility especially in the case when the custom toggle content has no text so the screen reader does not provide any useful overview for it.
