Add Namespace into android/gradle.build for suport to gradle 8+

[SeltonJeff]

Please add "namespace" into /android/build.gradle => android, for compatibility with gradle 8+.
EX:

android {
namespace 'reactnativeexceptionhandler'
compileSdkVersion getExtValue(rootProject,'compileSdkVersion',23)
buildToolsVersion getExtValue(rootProject,'buildToolsVersion', "23.0.1")

defaultConfig {
    minSdkVersion getExtValue(rootProject,'minSdkVersion', 16)
    targetSdkVersion getExtValue(rootProject,'targetSdkVersion', 22)
    versionCode 1
    versionName "1.0"
}
lintOptions {
    abortOnError false
}

}
