📝 Reusable attributes: Fix xref, update example

This commit makes two primary changes:

- Fix a broken `xref` link to the Fedora DEI Team documentation, which
  recently changed Antora component names from `/diversity-inclusion/`
  to `/dei/`.
- Update the example of an attributes file using the latest example from
  the Fedora DEI Team. This is a more comprehensive example of how to
  use attributes/partials based on the current practice in the DEI Team.
