feat: include "extraEnvVars" as part of the migration job

[Oscmage]

Description

From reading the code I see no way of providing the same extraEnvVars as done to the deployment for the migration job. The only way I can see is to directly add datastore.uri as part of the values file which is not something we want since it is a secret and something we want to commit to a git repository. It is from what I've found (please correct me if so) not possible to to use something like ExternalSecret to load the value dynamically rather than hardcoding it in the values file.

I'd like to be able to do something like

We are currently running this version of the chart in production and it works just fine.

openfga:
  extraEnvVars:
    - name: OPENFGA_DATASTORE_URI
      valueFrom:
        secretKeyRef:
          name: openfga-external-secrets
          key: OPENFGA_DATASTORE_URI

but it is currently not picked up by the migration job.

How it is done in the deployment file:

Line 326 in 40ea4e1

{{- with .Values.extraEnvVars }}

This makes sense to me given #134, but I'd like to tag @jon-whit to make sure there's nothing I'm missing
