Bug 8670 - Update POD of C4::Branch::GetBranches() to use TT syntax

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

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

Checked the POD with "perldoc C4/Branch.pm" before and after applying
the patch. The example now uses TT syntax, and looks sensible.
