Describe execution order of module hooks

[Tschakki]

Description

A description of the execution order of the module lifecycle hooks is missing - maybe in the section where lifecycle hooks of modules are explained: https://lisk.com/documentation/lisk-sdk/introduction/modules.html#lifecycle-hooks

Currently, the diagram states what happens with a block for a single module. It should have another diagram illustrating the lifecycle of a block in an app with multiple modules and their respective lifecycle hooks
