fix(messaging): improve MessageQueueTrigger logging and add tests

[dejii]

Fixes bug in MessageQueueTrigger.

When there are no matching providers, or multiple providers recognize the same queue, the logging code attempted to join provider class objects directly, causing:

TypeError: sequence item 0: expected str instance, SqsMessageQueueProvider found

MESSAGE_QUEUE_PROVIDERS contains a list of class objects

airflow/providers/common/messaging/src/airflow/providers/common/messaging/triggers/msg_queue.py

Line 38 in 5f29f4e

MESSAGE_QUEUE_PROVIDERS = [create_class_by_name(name)() for name in providers_manager.queue_class_names]

but .join([ ... ]) expects strings

airflow/providers/common/messaging/src/airflow/providers/common/messaging/triggers/msg_queue.py

Line 75 in 5f29f4e

", ".join([provider for provider in MESSAGE_QUEUE_PROVIDERS]),

Added new tests to cover various scenarios including:

• No available message queue providers.
• Queue not recognized by any provider.
• Collision where a queue is recognized by multiple providers.
