Version number in tutorial manifests for Azure needs updating to at least registry.k8s.io/external-dns/external-dns:v0.13.6

What happened: I'm new to AKS and External-DNS. I've been tasked with finding a way to update Azure DNS automatically when a deployment is made. I found External-DNS and have been trying to get the examples in the azure and azure-private-dns working but have spent a long time seeing the external-dns pod immediately enter a CrashLoopBackoff state. The log reported

level=fatal msg="failed to get token: no credentials provided for Azure API"

What you expected to happen:

The pod should go to state

pod/external-dns-57cf84df49-87bsx 1/1 Running 0 21s

and the logs should show

time="2023-11-10T18:15:38Z" level=info msg="Using workload identity extension to retrieve access token for Azure API."
time="2023-11-10T18:15:38Z" level=info msg="All records are already up to date"

How to reproduce it (as minimally and precisely as possible):

set the deployment container version to

registry.k8s.io/external-dns/external-dns:v0.13.5

Anything else we need to know?:

In the end I stumbled on the fact that the version in the document is a couple of releases out of date. I updated the realease version in the manifest to

registry.k8s.io/external-dns/external-dns:v0.13.6

and everything started working??

All that needs doing is updating the tutorial documentation I think. I tested with v0.14.0 and it works with that also.

I can make that happen.
