Introducing new enabled_on / disabled_on app blocks schema attributes (deprecating templates)

You can now use the new enabled_on / disabled_on app block schema attributes to specify where an app block can be used. These new attributes replace the existing templates attribute and work for both templates and section groups.

• Use the enabled_on attribute to limit an app block to specific templates and section groups.
• Use the disabled_on attribute to prevent an app block from being used in specific templates and section groups.
• These new attributes work for both app blocks and app block embeds.

Please keep in mind that you can use only one of enabled_on or disabled_on.
