I noticed that the `android_splash_screen` sample was outdated and was
not runnable due to gradle issues.
This commit fixes the Gradle setup for the `android_splash_screen`
sample.
Key changes include:
* Upgrading Gradle wrapper from version 6.7 to 8.7.
* Migrating to the plugins block in `settings.gradle` and
`app/build.gradle` for applying Android, Kotlin, and Flutter Gradle
plugins.
* Removing the outdated `buildscript` block from the root
`build.gradle`.
* Updating `compileSdkVersion` and `targetSdkVersion` to 34.
* Setting `minSdkVersion` to `flutter.minSdkVersion`.
* Adding the `namespace` property as required by newer Android Gradle
Plugin versions.
* Refactoring Kotlin constant declarations in `MainActivity.kt`.
