Add "Remove from workspace" button on resource page

[Emily Lepert]

Current behavior

If a user wants to clear their workspace, they have two options:

1. go to the page with all of their resources and select their resource and click "remove from workspace". The resource page has a button to redirect them to the all resources page for them to do this.
2. on the resource page, select all files in their workspace and click delete

Desired behavior

The ability to remove their resource from their workspace directly from the resource page. This action deletes all files in the workspace.
