Updating instructions

To update GameActivity to the latest version, do the following:

In //starboard/android/apk/app/build.gradle, update the dependency version for androidx.games::games-activity. The current version is 1.2.1, and you can find the latest version from [the AndroidX games release website] (https://developer.android.com/jetpack/androidx/releases/games).
Build Cobalt. This triggers gradle to downloaded the release package to its local cache (normally under the $HOME/.gradle folder).
Find the downloaded game-activity package, usually under $HOME/.gradle/caches/.... The directory structure should match the structure under //third_party/android_game_activity/include/.... You can use find with a specific file to locate the exact path for the package, as shown in the following example:
```
  find   ~/.gradle/caches   | grep   GameActivity.cpp
```
Copy all C++ files for the matching games-activity version to this directory (the directory that is hosting this README.md file). For example, with version 1.2.1, the path might be $HOME/.gradle/caches/transforms-3/355ab20937e7dabe38cca2293f9f651b/transformed/jetified-games-activity-1.2.1/prefab/modules/game-activity/include/game-activity/GameActivity.cpp, just pull the content from .../jetified-games-activity-1.2.1/prefab/modules/game-activity:
```
pushd ${cobalt_src_dir}/third_party/android_game_activity
rm -fr include module.json
cp -fr .../jetified-games-activity-1.2.1/prefab/modules/game-activity  third_party/android_game_activity/
popd
```
