Recommend using an APP_NAME variable instead of PRODUCT_NAME on 'Create flavors of a Flutter app' page

Describe the problem

The document suggests using $(PRODUCT_NAME) to change the display name of the app. However, changing this is not a good idea as one of its values seeps into the .xcscheme files of all flavors. Namely this is what you end up with:

flavor2.xcscheme

            <BuildableReference
               BuildableIdentifier = "primary"
               BlueprintIdentifier = "97C146ED1CF9000F007C117D"
               BuildableName = "flavor1.app"
               BlueprintName = "Runner"
               ReferencedContainer = "container:Runner.xcodeproj">
            </BuildableReference>

So you see flavor1 in flavor2's .xcscheme file. Better way is to create a new variable like APP_NAME as suggested here: https://sebastien-arbogast.com/2022/05/02/multi-environment-flutter-projects-with-flavors/#Preparing_Your_iOS_App

Expected fix

The document would not suggest editing and using PRODUCT_NAME.
