RDART-1087: Update compileSdkVersion to fix android:attr/lStar not found

[scris]

Pull request #1773 exists but was not merged for more than a month due to some configuration mistakes concerned by cla-bot, making #1774 unsolved for long.

This pull request includes exactly the same things of what #1773 included, aiming to speed up the merging of this important update, so that the "android:attr/lStar not found" error can be fixed when using Flutter SDK 3.24.

Is any update here ?

For those, who are looking for quick solution:

Add the following to the root-level android/build.gradle file:

subprojects {
    afterEvaluate { project ->
        if (project.hasProperty("android")) {
            project.android {
                compileSdkVersion = 31
            }
        }
    }
}

Make flutter clean

I think "OS Error: No such file or directory" is probably fault on your computer's side, and flutter clean and redo your task might help. But I'm not sure, it might be some other faults I had never seen. If you're willing to solve this before the official merge, I think the best way is to use the workaround from @Den-creator rather than pulling from my branch. Best regard.

Thank you for the configuration @Den-creator
