Tests: Replace unmaintained Bitnami Legacy Kafka image in testcontainers #33
Description
Description
I noticed that bulkerapp/app/testcontainers/kafka/docker-compose.yml utilizes the bitnamilegacy/kafka:3.7.1 image.
Since Bitnami has moved these images to a legacy repository, they are effectively frozen.
Proposed Solution
I suggest replacing it with the actively maintained alternative: soldevelo/kafka:3.7.1.
This image is a drop-in replacement that preserves the /opt/bitnami/... directory structure and supports the standard environment variables (like ALLOW_ANONYMOUS_LOGIN) used in your configuration. This ensures the test environment remains secure and functional without requiring changes to the setup.
I can submit a quick PR to update this image reference.
