AIP-84 Migrate the public endpoint Get Task to FastAPI #42874

Description

Currently the Get Task public endpoint is at api_connexion/endpoints/task_endpoint.py under get_task. We need to migrate it to the api_fastapi/views/public/tasks.py under a get_task or similar.

Features and functionality of the endpoint will remain unchanged.
