[Bug]: Command expansion error when using script for "config" values.

What happened?

Example when set the helm values for config:

config:
  server.routing.advertised_address: "$(hostname -i)"

Will see the following error during neo4j start up:

Failed to read config /config/neo4j.conf: Error evaluating value for setting 'server.routing.advertised_address'. $(hostname -i) is a command, but config is not explicitly told to expand it. (Missing --expand-commands argument?)

However, later in the log will see:

2024-03-26 08:49:35.605+0000 INFO  Command expansion is explicitly enabled for configuration
2024-03-26 08:49:35.605+0000 INFO  Executing external script to retrieve value of setting server.routing.advertised_address

Since command expansion is enabled by default, is there really an error going on here?

When trying to understand more about the error, I encountered the following line {{- $configImport := .Values.configImport -}} for user-config but couldn't find the reference for this value - what is this configImport and where does it get its value from?

The manual says neo4j.conf will not be used here, so how does user specified configurations gets to apply?

@tanvp112 just tried the below config and its working as expected

config:        
  server.routing.advertised_address: "$(bash -c 'hostname -i')"

helm install command

helm install standalone neo4j --set neo4j.password="password" --set volumes.data.mode="defaultStorageClass" --set neo4j.edition="enterprise" --set neo4j.acceptLicenseAgreement="yes" --set neo4j.name="demo" -f demo.yaml

@harshitsinghvi22 , can you advise where does Values.configImport gets it values from {{- $configImport := .Values.configImport -}} ? There is no such field in the values.yaml.
