Bug 35059: Display item location on item details (catalogue/moredetail.pl)

Bug 35059: Display item location on item details (catalogue/moredetail.pl)

This patch updates the item details template so that item location is
displayed along with information like collection and call number.

The template has also been modified to correct the label "Item
callnumber" to "Item call number."

To test, apply the patch and update an item, if necessary, to add a
shelving location.

- View the bibliographic details page of the record.
- Click the "Items" tab in the left-hand sidebar menu.
- Under the "Item information" subheading you should see a line for
  "Shelving location" just after the "Item call number" line.
- Confirm that the correct item location description is shown.
