Describe the bug
With the following directory structure:

I'd expect to use this pattern to include files in docset.yml
:
- file: reference/1password/index.md
- file: reference/abnormal_security/index.md
- file: reference/activemq/index.md
- file: reference/entityanalytics_ad/index.md
- file: reference/admin_by_request_epm/index.md
- file: reference/airflow/index.md
- file: reference/akamai/index.md
However, following this pattern results in all of the above pages being silently excluded from the table of contents:

Instead, the following pattern had be used to get the files to build to the table of contents:
- file: reference/1password.md
- file: reference/abnormal_security.md
- file: reference/activemq.md
- file: reference/entityanalytics_ad.md
- file: reference/admin_by_request_epm.md
- file: reference/airflow.md
- file: reference/akamai.md
Here's the PR where @colleenmcginnis is working on this content: https://github.com/elastic/integration-docs/pull/688.
This is potentially related to #443?
Expected behavior
I should be able to use the full path to include these files.
Steps to reproduce
