[ANDROID] serviceName plugin option is ignored

[marco-saia-datadog]

Describe what happened

The error tracking option serviceName is not picked up on Android, starting from v2.8.0 of Datadog React Native SDK.

Reported by @FrikkieSnyman on DataDog/dd-sdk-reactnative#879 (comment)

Steps to reproduce the issue

Use a custom serviceName

[
  'expo-datadog',
  {
    errorTracking: {
      serviceName: 'custom-service-name',
      iosSourcemaps: true,
      androidSourcemaps: true,
    }
  }
]

The android/app/build.gradle is modified as follows:

plugins {
    id("com.datadoghq.dd-sdk-android-gradle-plugin") version "1.14.0"
}

datadog {
    checkProjectDependencies = "none"
    serviceName = "custom-service-name"
}
apply plugin: "com.android.application"
apply plugin: "org.jetbrains.kotlin.android"
apply plugin: "com.facebook.react"
apply from: "node_modules/@datadog/mobile-react-native/datadog-sourcemaps.gradle"

Leading to serviceName not being picked up, due to the fact that the Datadog React Native SDK expects it to be in project.ext.datadog properties.

Expected outcome

The serviceName is defined in the project.ext.datadog properties, and the React Native SDK picks up the serviceName from datadog as a fallback for retro-compatibility.
