* [helm] Allow to pass extraEnv and extraEnvFrom to deployment

The chart relies on [external-secrets.io](https://external-secrets.io)
to pull the secrets. This might not be convenient for open source
community users. As such, let's complete the externalSecrets with `env`
and `envFrom` via respectively `.Values.extraEnv` and
`.Values.extraEnvFrom`.
