调用年龄范围框架的requestAgeRange，未弹出：是否要分享年龄的提示框

操作步骤：1:调用let eligible = try await AgeRangeService.shared.isEligibleForAgeFeatures，返回YES后，再次调用 let response = try await AgeRangeService.shared.requestAgeRange(ageGates:18, in: viewController)

                switch response {
                case .declinedSharing:
                    DispatchQueue.main.async {
                        completion(.declinedSharing, nil, nil)
                    }
                
                case .sharing(let swiftRange):
                    DispatchQueue.main.async {
                        let model = ARAgeRange(swiftRange: swiftRange)
                        completion(.sharing, model, nil)
                    }
