Kubenet is being deprecated. However, this page is still showing kubenet as default network configuration:

Correct the information.

Additional context
Add any other context about the problem here.

I made a fix here: MicrosoftDocs/azure-aks-docs#178
Unfortunately, there is no one write #sign-off. This should not involve any technical knowledge and only requires simple check.

Considered that the PR processing speed is so slow like in: MicrosoftDocs/azure-aks-docs#138, I am questioning the efficiency of AKS Doc Team. This "small" issue is surely not important, right?

I don't want to DM PG/PM one by one again for "improvement". I already contacted POC for this, but still no progress.
I am not getting paid for this. But this is slowly wearing off my patience. I no longer feel good to do such "feedback" or "contribution".
