Update Prompt Version

Updates metadata for a specific prompt version. This endpoint only supports updating the label_id field.

Prompt versions are immutable — their string, parameters, and model content cannot be changed after creation. To update prompt content, use PUT /prompts/{promptId} which creates a new version with the updated content.

PUT /prompts/{promptId}/versions/{versionId}
