Pull Request Overview

This PR updates the Helm upgrade command in the GCZ deployment documentation to improve readability and consistency. The command is refactored to use quoted variables and split across multiple lines for better clarity.

Key Changes:

• Modified the Helm upgrade command to use quoted environment variables ("$RELEASE_CHART_NAME" and "$NAMESPACE") instead of an unquoted variable reference
• Split the command across two lines for improved readability

The variable $RELEASE_CHART_NAME is introduced in this command but was not used previously (the original command used $CHART). This documentation should either define $RELEASE_CHART_NAME before this step or continue using $CHART for consistency with the variable that was presumably defined earlier in the documentation.

Suggested change

	helm upgrade -i "$RELEASE_CHART_NAME" . -n "$NAMESPACE" -f osdu_gcz_custom_values.yaml \
	helm upgrade -i "$CHART" . -n "$NAMESPACE" -f osdu_gcz_custom_values.yaml \
