fix: rename private DNS zone privatelink.dp.kubernetesconfiguration.azure.com

[baartch]

Overview/Summary

Regarding the documentation, the name of the private DNS zone is wrong:
https://learn.microsoft.com/en-us/azure/private-link/private-endpoint-dns#hybrid--multicloud

The documentation was wrong too and has been fixed Sep 2023:
https://github.com/MicrosoftDocs/azure-docs/issues/115266#issuecomment-1739208876

1. Insert dp. in all occurances of privatelink.kubernetesconfiguration.azure.com. This results in privatelink.dp.kubernetesconfiguration.azure.com.
   I changed all occurances except the ones in generateddocs. I hope this is correct.

Breaking Changes

The private DNS zone has to be recreated.

Thanks much for catching this and creating a PR, much appreciated!

I update the docs as the workflow to generate them automatically failed due to 403. Just a note for future PRs, but the forks inherit branch protections so recommend using a branch other then main for future PRs. Or you can also just generate them locally using guidance here as well: https://github.com/Azure/ALZ-Bicep/wiki/Contributing#manually-generating-the-parameter-markdown-files
