datastreams: `vocabularies update` crash

[tmorrell]

Package version (if known): v12

Describe the bug

The datastream vocabularies update command crashes. Changing a working vocabularies install command to update doesn't work as expected.

Steps to Reproduce

1. Set up a names vocabulary with pipenv run invenio vocabularies import --vocabulary names --filepath ./vocabularies-future.yaml

and

`names: readers:

• type: yaml args: origin: "./app_data/people.yaml" writers:
• type: service args: service_or_name: names `
  2. Change metadata in the people.yaml file
  3. Type pipenv run invenio vocabularies update --vocabulary names --filepath ./vocabularies-future.yaml
  4. See error

Expected behavior

Vocabulary gets updated
