• fixes [newrelic-logging] Invalid yaml generated when .Values.exposedPorts, .Values.resources, and .Values.fluentBit.fluentBitMetrics are all set #2057

Special notes for your reviewer:

Moves existing yaml lines to correct location for valid yaml generation. Currently when .Values.exposedPorts are set the lua-scripts volume mount entry is placed under <...>.ports when it should be under <...>.volumeMounts.
Additionally, this fixes a related bug where if .Values.resources is not set then the volume mount is not created.
