Improve dag_bundle_config_list Configuration in Airflow Helm Chart

This PR improves the dag_bundle_config_list configuration in the Airflow Helm Chart by allowing users to define DAG bundle configurations in a structured YAML format instead of requiring a JSON string directly in the values file.

Changes

• Added a new dag_bundles section under dagProcessor in values.yaml that allows users to define DAG bundles in a structured YAML format
• Created a Helm template helper function dag_bundles that automatically converts the YAML structure to the required JSON string format
• Set default value for dagProcessor.dag_bundles with a local DAG bundle configuration
• Updated config.dag_processor.dag_bundle_config_list to use the helper function
• Moved dag_bundles configuration under dagProcessor section for better logical grouping

Benefits

1. Better Readability: Long JSON strings in YAML files are difficult to read and maintain. The new structured format is much more readable.
2. Less Error-Prone: Manual JSON string construction is prone to syntax errors. The YAML format reduces the chance of errors.
3. Better IDE Support: IDEs can provide proper syntax highlighting, validation, and autocomplete for YAML structures.
4. Easier Maintenance: Adding, removing, or modifying bundle configurations is now straightforward.
5. Better Organization: DAG bundle configuration is now logically grouped under the dagProcessor section.

Usage

Users can now define DAG bundles like this:
