Code Review

This pull request correctly migrates the integration_test package to use UIScene APIs on iOS. The changes in AppDelegate and Info.plist are standard for this migration. The IntegrationTestPlugin is updated to get windows and screen bounds from the UIWindowScene, which is the correct modern approach. I have one suggestion to improve code readability and conciseness.

Based on the logs, It seems like the CI is yet to have the UIScene protocols

It seems like the CI runs pod lib lint integration_test.podspec --use-libraries and downloads the framework from cocoapods which seems to use Flutter 3.13.0 when i ran pod spec cat Flutter. We could either wait for the APIs to be integrated or make it backwards compatible

So this came up before in packages (flutter/packages#10484) and we decided to change it to pod lib lint --quick so that we wouldn't have to publish a new version of Flutter to CocoaPods. I think we should do the same here
