Maybe I should add that this is a feature from druid itself, not the operator https://druid.apache.org/docs/latest/operations/dynamic-config-provider/#environment-variable-dynamic-config-provider |

Description
This PR enhances the Druid Operator's documentation to improve clarity. It addresses the following:
Introduction of Environment Variables in Druid Configuration: A new section in the examples documentation introduces the use of environment variables within
common.runtime.properties. This provides a mechanism for greater configuration flexibility and security. Users can now manage sensitive information or environment-specific values externally, without directly embedding them in the Druid configuration. This was already being used on Allow possibilities to add env var to erase some config value #35 (comment)Practical Example of Environment Variables: A concrete example showcasing the utilization of environment variables for the metadata store configuration (
druid.metadata.storage.connector.*) is added. This example guides users on how to implement this new feature effectively.Key changed/added files in this PR
