Allow Kubernetes yaml style

[girafi]

We have lots of Kubernetes config files in yaml that list the env vars in the following style:

env:
- name: MY_KEY_1
  value: "value1"
- name: MY_KEY_2
  value: "value2"

We would love to also use the same yaml locally for running with your gorgeous and awesome fancy envVar plugin. Converting them to yaml dictionary is unfornunately quite a step always

Thanks for your care!
