Document capturing hook-level lineage

[kaxil]

#41482 was released. We should add documentation around it specifically some examples

Success criteria:

• How does a hook define this? do we have any examples?
• Is anything else covered than ObjectStorage
• do we only pull hook lineage if the operator methods don't exist? or do we do both, if both exist?
• do these get transmitted in the task complete event?

@kaxil, can I take up this one?
