managedZones creation not covered in the doc

Description

Tried to follow along the detailed docs (thanks!). Faced an error - which I think was not an intended experience ?

bash-3.2$ ./gcloud dns record-sets create rekor.xxx.com. \
> --rrdatas=$(./gcloud compute instances describe sigstore-rekor --format='get(networkInterfaces[0].accessConfigs[0].natIP)') \
> --type=A --ttl=60 --zone=xxx-com
API [dns.googleapis.com] not enabled on project [xxxxxxx]. Would you like to enable and retry (this will take a few minutes)? (y/N)?  y

Enabling service [dns.googleapis.com] on project [xxxxxxx]...
Operation "operations/acat.p2-314840182640-21001061-d775-40c6-8263-2775502ef2a6" finished successfully.
ERROR: (gcloud.dns.record-sets.create) HTTPError 404: The 'parameters.managedZone' resource named 'xxx-com' does not exist.

After creating the managedZone - I was able to proceed with the rest of the documentation.

Weird, I never had this issue just running through again. I will keep this open in case its seen again.
