Failed to compile for Android: Unresolved references in Gradle script

[matthunz]

Describe the bug
I've been getting this error for a little while now, but I'm not sure if it has to do with my SDK/JDK version 🤔 removing the lines with errors seems to solve this however.

FAILURE: Build failed with an exception.

* Where:
Build file '/home/matt/Documents/dev2/gen/android/app/build.gradle.kts' line: 42

* What went wrong:
Script compilation errors:

  Line 42:     kotlinOptions {
               ^ Unresolved reference: kotlinOptions

  Line 43:         jvmTarget = "1.8"
                   ^ Unresolved reference: jvmTarget

Steps To Reproduce
Create a new project with any template and run cargo android run.

Expected behavior
I think we can just remove those lines, doing so has fixed compilation for me on both platforms.
