Move additionalInitContainers to bottom in server-job.yaml

[ragutsky]

What was changed

Moved admintools.additionalInitContainers to the bottom in server-job.

Why?

Since additional init containers run first there isn't a way to add additional steps to server job after schema setup/update (for instance, add search attributes).

Checklist

1. Closes -

2. How was this tested:

• add value:

admintools:
  additionalInitContainers:
    - name: create-search-attributes
      image: temporalio/admin-tools:1.26.2
      imagePullPolicy: IfNotPresent
      command: ['/bin/sh','-c']
      args: ['temporal operator search-attribute create --namespace "my-namespace" --name="CustomId" --type="Keyword"']

• run command helm template demo charts/temporal -s templates/server-job.yaml
• check that added container is at the end

3. Any docs updates needed?

No
