DOC-5937 RDI source prep checklists

[andy-stark-redis]

We use these checklists in some of the other doc pages and I thought it might be useful to add them to some of the RDI pages, since they often involves lots of steps to follow. AI agents love these checklists, but if you think they are too intrusive for human readers then we can maybe keep them hidden in the page, so only AI tools can see them.

Let me know what you think of this example. I'll add similar checklists to the other pages if everyone's happy with them.

I do kind of find these checklists a little intrusive, but I'll defer to the RDI folks if they think customers will or won't like them.

[andy-stark-redis]

@cmilesb I've got a separate PR for an option to add the checklist into a page (for its AI/metadata value) but not show the interactive checklist to the user. I think I'll use this "hidden" version in the RDI pages for now

[andy-stark-redis]

@cmilesb I've added an option to add the checklist, but make it invisible to the human reader (although we are still discussing whether or not to add the interactive checklists in some places). I've added hidden checklists now in several places, including your AWS pages.

Please can you have a look at the AWS pages and let me know if you think the checklists would be acceptable from a source maintenance point of view (ie, if they make the page a nightmare to maintain, then maybe we don't want them, or we want a simpler version).
