fix: enable missed return types for generic

[hallvictoria]

Description

Implicit output is now enabled for generic bindings, so the worker needs to support returning the same python types as it did when implicit output wasn't enabled. The other types that have been returned include:

• dict
• list
• int
• double
• bool

TypedData only supports string, json, bytes, stream, http, int, double, collection types, and model_binding_data. Therefore, types that are not supported (dict, list, bool), are converted to supported types (json, json, int respectively).

Added E2E tests for all supported return types to check if the functions are executing correctly and unit tests to test the return values.
