Describe the feature:
This feature request is for the capability to export detection rules created using the Kibana GUI directly into TOML format. Currently, there is functionality available to import rules from JSON format within the elastic/detection-rules repository under the "import-rules" functionality. However, there is no direct way to export these rules into TOML format from the Kibana interface.

Describe a specific use case for the feature:
Providing a direct export option to TOML format will greatly facilitate the codification and version control of detection rules. By implementing this feature, users will gain a more flexible, efficient, and robust way to manage their detection rules, enhancing their overall security operations and workflows.
