Bug 10765 - [SIGNED-OFF] Update POD of C4::Koha::GetSupportList() to use TT syntax

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

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

This patch works as advertised (verified with "perldoc C4::Koha"),
for GetSupportList, but it does not fix a a similar example for
GetItemTypes, getauthtypes and getframework in the same file,
which still has the old template syntax. So a followup or separate
bug(s) for those are called for.

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