Empty assemblies

[kleinffm]

downstream/assemblies/terraform-aap/assembly-terraform-product.adoc and downstream/assemblies/vault-aap/assembly-vault-product.adoc continue to throw an "AsciiDocDITA.ShortDescription:Assign [role="_abstract"] to a paragraph to use it as in DITA." error because they are empty except for a title. Neither have any text to add [role="_abstract"] to, nor any include statements.
