helm: replace order of global and local values

[netanelC]

Describe the bug
Currently, global values are more important than local values, it is supposed to be the opposite.
You can see _helpers.tpl:

ts-server-boilerplate/helm/templates/_helpers.tpl

Lines 60 to 69 in adbbe33

	{{/*
	Returns the environment from global if exists or from the chart's values, defaults to development
	*/}}
	{{- define "ts-server-boilerplate.environment" -}}
	{{- if .Values.global.environment }}
	{{- .Values.global.environment -}}
	{{- else -}}
	{{- .Values.environment | default "development" -}}
	{{- end -}}
	{{- end -}}
