text: Title: [DOC] References to aeon.utils.registry.COLLECTIONS_DATA_TYPES
  Body: ### Describe the issue linked to the documentation
  
  There are several references in the docs to 
  `aeon.utils.registry.COLLECTIONS_DATA_TYPES`
  in the docs. This does not exist. I think it should be just
  `aeon.utils.COLLECTIONS_DATA_TYPES`
