   I took a crack at this but I don't think it is easily possible to make the env_vars formatting nicer. I tried adding this line to the k8s pod operator ```    template_fields_renderers = {"env_vars": "json"}```
   
   The env_vars look like this in the UI afterwards:

   In the past it looks like env_vars was just a dict so it was easy to format it with the json lexer however now env_vars are converted to a list of env_vars with [this function](https://github.com/apache/airflow/blob/2b2d97068fa45881672dab6f2134becae246f3f3/airflow/providers/cncf/kubernetes/backcompat/backwards_compat_converters.py#L90-L105).
   
   Perhaps there is a way to still make this work, but it isn't as straight forward as I was hoping.
