Upgrade the Gradle version in the project template

[blasten]

Gradle 6.0 came out recently: https://docs.gradle.org/6.0/release-notes.html

The Flutter template currently uses 5.6. However, 6.0 might become the default version for new Android apps generated by Android Studio.

For context, this is already the case: #46260 (comment) if a Flutter app is edited on Android Studio.

From #51464:

Android Studio 3.6 was released recently, and it seems it now requires a higher version of Gradle than the one Flutter is using.

Steps to Reproduce

1. Run flutter create bug.
2. Update the files as follows: android/build.gradle -> classpath 'com.android.tools.build:gradle:3.6.0'
3. Try to run or build the app for Android.
4. The exception provided in the Logs section will appear.

Flutter projects are currently created using Gradle version 5.4.1, but to make it compatible with newer versions of Android Studio, it could be bumped to, at least, 5.6.4, or even 6.2.1 (latest).

dependencies {
        classpath 'com.android.tools.build:gradle:3.6.2'
