Bug 10763 - [SIGNED-OFF] Update POD of C4::Creators::Lib::html_table() to use TT syntax

This patch updates the example template syntax in the POD for
C4::Creators::Lib::html_table() to use Template Toolkit syntax.

To test, view the POD for C4::Creators::Lib::html_table() and confirm
that it looks correct.

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