…ous tasks.

- Utilized environment variables with default values for RabbitMQ hosts.

- Updated Taiga events RabbitMQ host configuration to use the environment variable `TAIGA_EVENTS_RABBITMQ_HOST`, with a default value of 'taiga-events-rabbitmq'.
- Revised asynchronous tasks RabbitMQ host configuration to use the environment variable `TAIGA_ASYNC_RABBITMQ_HOST`, with a default value of 'taiga-async-rabbitmq'.

This enhancement provides more flexibility in configuring RabbitMQ hosts for Taiga events and asynchronous tasks. Utilizing environment variables allows for easy customization, and default values ensure seamless deployment with minimal configuration.
