Bug 10764 - Update POD of C4::Items::GetItemStatus() to use TT syntax

This patch updates the example template syntax in the POD for
C4::Items::GetItemStatus() to use Template Toolkit syntax.

To test, view the POD for C4::Items::GetItemStatus() and confirm that it
looks correct.

This patch works as advertised (verified with "perldoc C4::Items"),
for GetItemStatus, but it does not fix a a similar example for
GetItemLocation in the same file, which still has the old template
syntax. So a followup or separate bug for that is called for.

It seems the default option is not in used in templates.
