### The Feature

Please allow the Helm chart user better control of the annotations of the migrations job, like changing the ArgoCD or Helm hook stage (PreSync, Sync, etc.) or adding custom annotations. They are important for managing the ordering and lifecycle of the migrations job in a custom deployment context.

### Motivation, pitch

Helm chart migrations job annotations are currently very rigid, only providing to run in a specific ArgoCD or Helm hook sync stage, without allowing the user to override them.

This can lead to problems for example when using custom database deployment and needing to sequence the job after the database is synced, otherwise the hook job will run in ArgoCD _PreSync_ stage, blocking the progression of the deployment before the database can be deployed in the _Sync_ stage.

Will try to propose a MR.
