build: upgrade Gradle and dependencies

Upgraded Gradle plugin to version 8.1.0 and updated the wrapper to use Gradle 8.0. Updated build settings to modern standards, including non-final resource IDs and non-transitive R class. Moved lintOptions block to the proper lint configuration block in build.gradle. Removed the redundant package attribute from the AndroidManifest.xml since it's now defined in the namespace block.

These updates address compatibility issues and take advantage of new features and performance improvements provided by the latest Gradle version.
