Spaces in serverless

[joepeeples]

Resolves https://github.com/elastic/security-docs-internal/issues/31. Also fixes #6019.

Preview

• Click the link in the comment below, then in the Security card click View serverless docs.
• Navigate to: Elastic Security UI → Spaces and Elastic Security

Note that we're no longer trying to omit "Kibana" from serverless docs, as that no longer seems to be a requirement (it's all over the UI). So this content mostly mirrors the ESS version in sometimes referring to spaces as "KIbana spaces," though in some instances this has been shortened to just "spaces" for simplicity.

Left one question, otherwise 🚢 it

[benironside]

Bit confused why we're linking to detections requirements when the sentence is talking about ES and Kib.

[benironside]

Would it make sense to link here instead?

[joepeeples]

Hm, good question. This page mostly mirrors the stateful version, which also points to the detections requirements, so this was just going for parity. But it does seem a little weird to focus on just detections requirements, when several other features also have space-bound privilege requirements.

I think something like this general requirements page might be a better link here, since it gives info on space & index privs AND points to other feature-specific req pages. I pushed commit 8fb2584 to change to both serverless and stateful...
