debezium/dbz#1810 Add automated E2E tests for the mysql tutorial example

[KMohnishM]

Description

Fixes debezium/dbz#1810

This PR introduces automated end-to-end testing for the standard MySQL flow in the tutorial example, utilizing the shared YAML-driven test runner established in #406.

Changes

• Tutorial E2E Test Manifest: Added tutorial/test.yaml which defines the test workflow:
  • Starts the services via docker-compose-mysql.yaml.
  • Registers the MySQL connector using register-mysql.json.
  • Executes a database update query on the inventory.customers table using the MySQL client.
  • Consumes the dbserver1.inventory.customers Kafka topic to verify that the CDC event was successfully captured and streamed.

Verification

• Tested locally via python3 scripts/run-example-test.py tutorial.
• Confirmed that the connector registers successfully and the UPDATE operation is successfully published to Kafka.

Checklist

• If the changes include a new example, I added it to the list of examples in the README.md file
