Hello! I'm attempting to use the automation API to set an array in my yaml config file. I have a python list of `['us-east-1', 'us-east-2', 'ap-northeast-1', ...etc...]` and the end goal would be something like this in my config yaml
```  aws:regions:
    - "ap-northeast-2"
    - "ap-northeast-3"
    - ...etc...```
My python snippet is
```stack.set_config(f"aws:regions", auto.ConfigValue(value=regions))```
but that throws `TypeError: expected str, bytes or os.PathLike object, not list`

What is the best/correct way to set yaml arrays with the python automation API? Thanks you!

I was able to get this kind of working with JSON with the exception of a strangely formatted yaml
```config:
  aws:regions: '["us-east-1", "eu-central-1", "ap-southeast-2", "ap-northeast-1"]'```
*automation.py*
```stack.set_config(f"{project}:regions", auto.ConfigValue(value=json.dumps(regions)))```
*pulumi.py*
```regions = json.loads(config.require("regions"))```
