feat: pass mqtt_broker_type to infra module for IoT Core support

When mqtt_broker_type is set to "iotcore", the infra module now creates
the aws_iot_topic_rule and associated IAM resources needed to route MQTT
messages from spacelift/writeonly/# to the SQS queue. Without this,
worker messages (heartbeats, worker_ready, run_complete) never reach
the drain and runs get stuck after job assignment.

Also bumps the infra module to v2.2.0 which includes the IoT Core
topic rule support in its SQS submodule.
