Support for YAML anchors and aliases?

[why-not-try-calmer]

I would seem that, as of the latest version, this action doesn't support anchors and aliases. For example if, in my docker-compose.yml file, I define a service as:

  service1: &service1-config
  service2:
    <<: *service1-config

the action will throw on the alias (<<). Is there any plan to support this syntactical feature in an upcoming release?

@why-not-try-calmer yq version used by the action supports anchors and aliases. The problem was that I had to ignore services with no image to avoid errors like this one:

Error: cannot match with !!null, can only match strings. Hint: Most often you'll want to use '|=' over '=' for this operation

Is that the same one you were having?
