Fix schemas validation in CI

[Artifizer]

Need to resolve all the $ref schemas

Example:

  --spec=draft7 \
  -c ajv-formats \
  --strict=false \
  -s examples/gts.x.core.events.type.v1~x.core.audit.event.v1~x.marketplace.orders.purchase.v1~x.marketplace.order_purchase.payload.v1~.schema.json \
  -r "examples/gts.x.core.events.type.v1~x.core.audit.event.v1~x.marketplace.orders.purchase.v1~.schema.json" \
  -r "examples/gts.x.core.events.type.v1~x.core.audit.event.v1~.schema.json" -r "examples/gts.x.core.events.type.v1~.schema.json" \
  -d examples/instance.json
