Bug 36295: Space out content blocks in batch record deletion

This patch adds a float-clearing line break to the batch record deletion
template so that the "Record type" section has visual separation from
the record number submission tabs.

To test, apply the patch and go to Cataloging -> Batch record deletion.

There should be padding between the two sections.
