Docker compose instructions for creating keycloak admin account

[JMuff22]

Hi, should the documentation have instructions for creating the admin keycloak account with

docker exec keycloak /opt/jboss/keycloak/bin/add-user-keycloak.sh -u <USERNAME> -p <PASSWORD>

Under https://docs.waldur.com/admin-guide/deployment/docker-compose/ . Running this command off the develop branch with image: 'quay.io/keycloak/keycloak:22.0' results in stat /opt/jboss/keycloak/bin/add-user-keycloak.sh: no such file or directory: unknown . IIRC keycloak dropped the creation of the admin user this way and instead uses environment variables KEYCLOAK_ADMIN and KEYCLOAK_ADMIN_PASSWORD.
