chore: generate remaining output type metadata

[ktinubu]

Generate output type metadata for subscription_names, subscription_paths and topic_labels

For subscription_names, and subscription_paths autogeneration gave a tuple:

type:
          - tuple
          - - string
            - string
            - string
            - string

Where the number of strings depended on the number of subscriptions I specified in my terraform.tfvars:

...
pull_subscriptions = [
    {
      name                 = "pull"
      ack_deadline_seconds = 10
    },
    {
      name                 = "pull2"
      ack_deadline_seconds = 10
    },
     {
      name                 = "pull3"
      ack_deadline_seconds = 10
    },
     {
      name                 = "pull4"
      ack_deadline_seconds = 10
    },
  ]

I generated the output type metadata using on 1 subscription
