Looks good, let's have CI green and another CoPilot review

Pull request overview

This PR extends the Edge3 provider’s EdgeExecutor/worker path to support Airflow 3.3+ ExecuteCallback workloads (in addition to ExecuteTask), including API schema updates and unit tests to validate serialization, queuing, and command parsing.

Changes:

• Add ExecuteTypeBody/callback identification helpers and route/worker typing updates to accept callback workloads.
• Extend EdgeExecutor queuing + worker API command parsing to recognize and deserialize ExecuteCallback.
• Add/extend unit tests and update EdgeExecutor documentation + worker API OpenAPI schema to reflect the new workload shape.

Hi jens! Thanks for review!
I've tested this pr with airflow-core (main) and it works well.
There is issue the callback state is stuck in QUEDED state but it will be fixed in #66141
