fix(task): call vTaskDelete at end of std::thread in task::run_on_core_non_blocking

[finger563]

Description

• Ensure the detached task function calls vTaskDelete(nullptr) instead of returning. It is not needed in the Task itself because we do a join on that thread instead of detaching

Motivation and Context

Ensures that we follow the spec for what you must do when exiting the return function in FreeRTOS tasks under all conditions.

How has this been tested?

Building and running task/example on QtPy ESP32s3.
