[Internal]: Update 'metrics reference' to explain which integrations pod, container and AWS metrics come from

[roshan-elastic]

Description

In https://github.com/elastic/observability-dev/issues/4716, we are going to be making our infra inventory UI and inventory rules which use 'Kubernetes pods', 'Docker Containers' and the various 'AWS' entity types clear that they work with the data format the integrations work with.

Specifically, we're trying to ensure that OTel data doesn't 'bleed in' to the UI and cause confusion with users so we want to make it clear what data the UI does and doesn't work with.

This issue is to update docs for container metrics, pod metrics and AWS metrics to make it clear which integrations are supported (as we have done with the host metrics docs).

Oops. It looks like @theletterf had a lengthy discussion with y'all already on this topic. Fabri if this issue should be on your board instead, please feel free to move it back. I saw Infra Inventory and immediately thought of Obs Exp.

Same as in the other task — I'm OK with supporting Exp team with this update and them owning it.

Hey all,

This now has all of the information required to update the docs (or at least discuss it so we can figure out what to do).

Feel free to reach out whenever.

Note : We'll be updating the UI to refer to these docs in 9.3 so it would be great to ensure they're updated in time for when the changes go live in serverless - likely around 15th Dec
