DO NOT MERGE yet

I'm just putting this into draft to make sure it doesn't get merged before the CI updates are made in the logstash repo. 🙂

My note in elastic/logstash#17701 wasn't clear. 🙈 To rerun the check, you need to click the three dots next to the check, click View details, and then click Re-run jobs. In this case I chose to just Re-run failed jobs.

I know the docs eng team is dealing with something in docs-builder right now so maybe we can hold this, and @reakaleek can merge when it's safe?

Interesting! My approach kicked off a new test cycle, but it didn't actually pass. :-D

These changes will only have an effect after a docs-builder release and if the docs-internal-workflows workflow is updated to the latest version.
