knowledge: ground the Logic App agent in the annotated WDL schema

The raw 2016-06-01 schema rejects definitions Azure itself emits.
Validating the 87 workflow definitions in the estate against it, only 13
of the 35 whole definitions pass; the annotated build passes all 35.

Grounding an agent in a schema that redlines correct code teaches it to
write incorrect code, so the source now points at the annotated build in
terraform-azapi-logic-app-workflow: 21 notes explaining the constructs
and the run-time traps, plus 5 corrections each recorded with its reason
under x-annotation.corrections.

YAML rather than JSON because the notes render as readable literal
blocks and it is 30 percent smaller, which matters against the uploaded
knowledge budget.
