Fix Castor HelmChart - Quote Environment Variable INITIAL_FRAGMENT_SIZE

[kindlich]

In K8s, Env variables are quoted -> Applying the Helmfile can fail since currently the 1000 fragment size is not quoted.

castor/castor-service/charts/castor/templates/deployment.yaml

Lines 41 to 42 in 0eaaa5f

	- name: INITIAL_FRAGMENT_SIZE
	value: {{ .Values.castor.initialFragmentSize }}

Change to either "{{ .Values.castor.initialFragmentSize }}" like for the Redis Port,
or {{ .Values.castor.initialFragmentSize | quote }}
