If a declaration is named "properties" then we can't write a valid vocabulary for it

Bug Report 🐛

If we have a model like

@Test2('world')
namespace [email protected]
@Term('A nice properties term')
concept properties {
  @Term('A cool string')
  o String someString
}

and run concerto extract-decorators --models MODEL.cto --removeDecoratorsFromSource true we get the following vocabulary.yml:

locale: en
namespace: [email protected]
declarations:
  - properties: A nice properties term
    properties:
      - someString: A cool string

Correct me if I'm missing something but that is an invalid YAML file due to the duplicated properties key. Trying to apply this vocab gives:

concerto decorate --models com.example.e2e.a.cto --vocabulary vocabulary_0.yml
10:29:53 - ERROR: YAMLParseError: Map keys must be unique at line 5, column 5:

  - properties: A nice properties term
    properties:

Expected Behavior

I'm not sure how/if we should handle this case or if there is a way to write a vocab for the properties concept in the above model.
