Describe the bug

SwiftLint is making error to Typed-Error which is introduced in Swift 6. It seems that it's parsing Typed-Error as function's parameter.

//  JourneyRepository.swift
//  MSDomain

import SwiftData

import Entity
import MSError

public protocol JourneyRepository {
    func fetchJourneys(in region: Region) async throws -> [Journey]
    func fetchTravelingJourney() async throws(JourneyError) -> Journey
    @discardableResult
    func saveJourney(_ journey: Journey) async throws(JourneyError) -> Journey // Error this line
}
