Add back zeebe configuration to our helm values

[rodrigo-lourenco-lopes]

Describe the issue:

Add zeebe configuratitions to our helm values here, this can be done through core.configuration but this will overide the defaults in the config values in core.configmap in the camunda-platform-helm repo, see:

camunda-platform-helm/charts/camunda-platform-alpha/templates/core/configmap.yaml

Lines 17 to 21 in 75a1a16

	application.yaml: |
	{{ .Values.core.configuration | indent 4 | trim }}
	{{- else }}
	application.yaml: |
	{{ if .Values.global.identity.auth.enabled }}

These configurations were commented out in our values.yaml in this PR.

One possible solution is to append this configuration at the end of the defaults in the camunda-platform-helm core.configmap.yaml since spring reads the configuration sequentially and would override any repeating config, instead of deleting the defaults.
