Currently, the filter is button on mobile:
It should be changed to a toolbar, with the following details:
- The filter is not a button, but a full-width toolbar flush under the "Suggested edits" header
- There is a dropdown arrow in the RHS of the toolbar
- Filter text should not be bolded, and should be vertically centered in the filter bar
- While the label on desktop says "Easy, Medium edits", on mobile it should just be "Easy, Medium"
