Use generic revision overview

Problem/Motivation

#2446011: Show container revisions added revision tab overview specifically for Collect. On ther side, Drupal 8.2.x core provides a RevisionLogInterface while #2462731: Check RevisionLogInterface for summary and provide is going to provide Diff's revision overview. We should update Collect with the recents changes accordingly.

Proposed resolution

From #2462731: Check RevisionLogInterface for summary and provide #19:

Switch away from the own Controller for revisionOverview to the generic Entity revision tab and then implement the interface to offer a generated summary.
