docs: fix OpenAPI url of cpu profiler endpoint

[jansegre]

Motivation

When going through the docs with @BrunoCampana we noticed that this endpoint wasn't showing up on the docs.

Acceptance Criteria

• The correct endpoint for the "top API" (cpu profiler) is /top and the OpenAPI should use that, /profiler is used by a different endpoint and using it causes one to overshadow the other.

Checklist

• If you are requesting a merge into master, confirm this code is production-ready and can be included in future releases as soon as it gets merged
