chore: use confluent kafka image for tests

[rarguelloF]

Replace docker.redpanda.com/redpandadata/redpanda for confluentinc/confluent-local docker image for Kafka tests.

The sarama tests are currently flaking with the following error:

    ibm_sarama.go:127: 
        	Error Trace:	/home/runner/work/orchestrion/orchestrion/_integration-tests/tests/ibm_sarama/ibm_sarama.go:87
        	            				/home/runner/work/orchestrion/orchestrion/_integration-tests/tests/ibm_sarama/ibm_sarama.go:127
        	            				/home/runner/work/orchestrion/orchestrion/_integration-tests/utils/suite.go:77
        	            				/home/runner/work/orchestrion/orchestrion/_integration-tests/tests/ibm_sarama/gen_test.go:18
        	Error:      	Received unexpected error:
        	            	kafka: client has run out of available brokers to talk to: kafka: error decoding packet: message of length 1213486160 too large or too small
        	Test:       	TestIntegration_ibm_sarama
        	Messages:   	failed to create producer

We suspect it might be caused by the test starting before the container being fully ready. The confluent kafka testcontainers module seems to have smarter readiness check logic than the redpanda one, so hopefully this change solves the issue.
