[keycloakx] doc typo mixup between db and admin username/password

[thomas-riccardi]

https://github.com/codecentric/helm-charts/tree/master/charts/keycloakx#creating-a-keycloak-admin-user

The keycloakx README talks about admin user creation, but mentions environment variables for the database:

• KC_DB_USERNAME
• KC_DB_PASSWORD

I believe the correct env vars are:

• KEYCLOAK_ADMIN
• KEYCLOAK_ADMIN_PASSWORD
