[Bug] exclude_export_details export flag also excludes exceptions and exception lists

[Vexil-Derivative]

Describe the Bug

When exporting detection rules via the API, setting exclude_export_details to true will only output the rule objects, excluding the exceptions and exception lists. Setting it to false exports the rules, exceptions, exception lists, and a summary line at the end of the file. The documentation states this flag should only exclude the summary line, so this behavior is unexpected.

To Reproduce

1. Create at least 1 custom rule and add an exception
2. Run the following 2 POST requests:
   POST <kibana host>:<port>/api/detection_engine/rules/_export
POST <kibana host>:<port>/api/detection_engine/rules/_export?exclude_export_details
3. Compare the two responses, note the second one does not include the exception logic.

Expected Behavior

The exclude_export_details flag should only exclude the final summary line. All rules and exception objects should be output regardless as to how this flag is set.
