The overview of application servers (https://docs.camunda.org/manual/7.10/introduction/supported-environments/#container-application-server-for-runtime-components-excluding-camunda-cycle) should make clear that this is only relevant for shared-engine setups.

For example, we can add a subsction "Embedded Engine" that explicitly says that an embedded engine is supported in all app servers and a subsection "Shared Engine" that then lists the currently supported servers.
