[Request] Entity Risk Scoring available in multiple Kibana Spaces

Description

Users have requested the ability to run Entity Risk Scoring in multiple Kibana Spaces. This change removes the previous restrictions preventing users from doing so.

From a docs perspective, this simply means that we can now remove the "Known limitation" from the documentation here.
