Update documentation page examples to better reflect their titles

The title of each example is not representative of the actual result of the macro, which can cause confusion for those just learning how to use AWMKanbanMacro.

Also, this page uses the Help Application as a data source, which makes it hard to follow (object field names are databaseList1 or boolean1, which are not descriptive).

For these examples, these are the actual results:

• Kanban of Movies by genre showing the director field
  • Shows a board for each director, showing genre and seen fields as description for each card
• Kanban of Movies showing the director field, only showing a subset of directors
  • Same as the first example, but only shows one director column
• Kanban of Movies by genre showing the director field only comedy movies
  • Same as the first example, but only displays cards for objects with the seen field set to false
