The Validate and Publish all documents option should appear only for specific users

Preconditions: Have a page sent to moderation and one to validation.

Currently, as a Contributor when accessing the Overview page the user can see the "Validate all documents" and "Publish all documents" options. The buttons can be clicked but the message "A problem occurred during the validation of document XXX" or "A problem occurred during the publication of document XXX" appears.

The options should be visible only to users that can validate and publish a doc.
