• Fixes [AvoidAdditionalProperties] Errors should only be reported once per source code location (ignore $refs) #697

Verified it fixes the full spec in a local end-to-end test:

$ npx autorest --v3 --spectral --azure-validator --semantic-validator=false --model-validator=false \
  --openapi-type=arm --openapi-subtype=arm --use=@microsoft.azure/openapi-validator@2.2.2 \
  --tag=package-preview-2024-04 specification/desktopvirtualization/resource-manager/readme.md \
 | grep -i avoidadditionalproperties

FYI I believe the resolved is defined here:
https://docs.stoplight.io/docs/spectral/d3482ff0ccae9-rules#resolved

Thanks. After reading that, I feel even more confident this rule should use resolved: false.
