[watermill-kafka] use github.com/IBM/sarama

The go.mod still says: require github.com/Shopify/sarama v1.38.0

The sarama lib is now available under https://github.com/IBM/sarama, this should be reflected in the go.mod (although there is some forwarding from https://github.com/shopify/sarama to https://github.com/IBM/sarama)

otelsarama would also need to be replaced as it is deprecated. The most 'popular' (only?) replacement is dnwe/otelsarama. See also https://github.com/IBM/sarama/issues/2510.
