Fix gradle config by adding missing settings and dependencies

[JEreth]

Thank you for your work. We were playing around with your plugin and had some issues at building it for Android. We were able to fix it by adding some missing parameters and dependencies in the build.gradle file. Maybe this helps someone who is stumbling over this plugin

Hi @JEreth,

I made some tests and propose the corrections, please check my changes using this gist https://gist.github.com/maximzhemerenko/6b3b799d819a5a0e941db4a59fc8a9b8

It contains the next changes:

1. I replaced project.hasProperty to rootProject.hasProperty calls because previous implementation returned me wrong result.
2. moved kotlinVersion to buildscript's ext section, because in buildscript section I cannot retrieve data from global ext section
3. Renamed kotlinVersion to kotlin_version because I see this key name here https://github.com/ionic-team/capacitor/blob/main/android/capacitor/build.gradle

Could you please test changed gradle file in your project and if yes, change in this pull request and write me again? If after changes your app will compile I will merge this pull request
