Make `erp5_configurator_standard` use `erp5_configurator_standard_categories`.

Since this is the business templates for standard (SME) configurator categories,
it seems logical to install this business template when installing SME configuration.

Before these changes, standard configurator was using a spreadsheet ( `standard_category.ods` ) to define the categories. Now this spreadsheet is almost empty, it only contain group and site that are custom and the configurated instance will install `erp5_configurator_standard_categories` business template.

The main goal was to make generated configuration use unit conversion module instead
of the obsolete quantity properties on quantity unit categories, but I thought it would make sense to use this `erp5_configurator_standard_categories` business template that is otherwise not used.
