Env Var Override

I've got a question, possibly a behavior question, about setting environment variables for the deployment:
```
env:
AUTHENTIK_POSTGRESQL_HOSTNANE: [redacted]
AUTHENTIK_POSTGRESQL__NAME: [redacted]
```

However when I create a release like this, deployment ends up failing because it can't reach postgres, and when I look at the deployment the `AUTHENTIK_POSTGRESQL__HOSTNAME` and `AUTHENTIK_POSTGRESQL__NAME` variables are defined twice. Once with my values, and once with seemingly default values. From the deployment template it looks like that's happening because of https://github.com/goauthentik/helm/blob/b4911f0e82a94244dc5dbb95adc1a93d36ac2d3a/charts/authentik/templates/deployment.yaml#L44 So I guess what I'm wondering is if it's possible to merge those two sources of env vars rather than concatenating them.
