 * Send a notification to all users who manage a specific project, excluding the user sending the notification.

 * This function retrieves all users managing the project specified by `$projectUri` (excluding the current user)
 * and adds a new notification to their `notifications` field, stored as a YAML-encoded array.
 * If the `notifications` field is empty, an empty array is initialized before appending the new notification.
 * In case of an error during update, an exception is thrown with the error message and line number.
 *
 * @param array $notificationData An associative array containing the notification data to be added.
 * @param string $projectUri The URI of the project associated with this notification.
 * @throws Exception If an error occurs while updating a user's notifications.
