Docs: Broken link to KubernetesPodOperator

Apache Airflow version: 1.10.9 (latest on docs site)

Kubernetes version (if you are using kubernetes) (use kubectl version):

Environment:

• Cloud provider or hardware configuration:
• OS (e.g. from /etc/os-release):
• Kernel (e.g. uname -a):
• Install tools:
• Others: What happened:

Go to https://airflow.apache.org/docs/stable/kubernetes.html, click on KubernetePodOperator, it sends you to the Executor instead.

What you expected to happen:

I expect to arrive on the KubernetesPodOperator page. Looking at the code, the link points to a page that is now gone.

• rst code with link to old page https://github.com/apache/airflow/blame/1c5e105db7e740540e6b2453b3bfb016925c1e07/docs/kubernetes.rst#L31
• old page is present on readthedocs https://airflow.readthedocs.io/en/latest/howto/operator/index.html
• old page is not present on the new docs https://airflow.apache.org/docs/stable/howto/operator/index.html

How to reproduce it:

Go to https://airflow.apache.org/docs/stable/kubernetes.html, click on KubernetePodOperator, it sends you to the Executor instead.

Anything else we need to know:

Has been cherry-picked to 1.10.10rc2

I got it. The problem is only in the 1.10 series. In Airflow 2.0 this problem is gone.

Aah ok got you.

Thanks for the PR.
