Upgrade templates to AGP 8.7/Gradle 8.10.2 (#157872)
These are the versions we use in test, as of https://github.com/flutter/flutter/pull/157617.

Motivated by noticing a warning with the old template version:
```
This Android Gradle plugin (8.1.0) was tested up to compileSdk = 33 (and compileSdkPreview = "UpsideDownCakePrivacySandbox").
You are strongly encouraged to update your project to use a newer
Android Gradle plugin that has been tested with compileSdk = 35.
```
