feat(chart): allow valueFrom in env config of components (#40095)

[dada-engineer]

This fixes #40095 and allows the users of the official helm chart to add a valueFrom specification (for secret and configmap references) to the env config of components (most of them use the container_extra_env functions defined in _helpers.yaml).
