[deprecations/dataviews]: Check in all spaces (#202354)

## Summary

In order to show all potential deprecations, the SO request should
include all spaces by appending `namespaces: ['*']`.

This PR adds that, although it doesn't change the test (which, IMO,
should include the offending space). Feel free to commit to this PR or
to create a follow-up (whatever you prefer).
