Plugin cannot be applied as documented

Trying to apply the plugin as described in https://github.com/android/project-replicator/blob/master/docs/USAGE.md results in multiple build errors, at various times:

```
* What went wrong:
A problem occurred evaluating project ':host-api-demo'.
> KOTLIN_STAT_ENABLED_PROPERTY
```
```
* What went wrong:
A problem occurred configuring project ':host-api-demo'.
> com.android.builder.errors.EvalIssueException: compileSdkVersion is not specified. Please add it to build.gradle
```
```
* What went wrong:
A problem occurred evaluating project ':host-api-demo'.
> Could not initialize class org.jetbrains.kotlin.gradle.plugin.KotlinGradleBuildServices
```

These Android modules do have compileSdkVersion (or compileSdk using newer dsl). Some modules are _not_ Android modules.

What worked for me was to move the buildscript/classpath entry from build.gradle into settings.gradle's pluginManagement block, add the plugin by id to settings.gradle's plugin{} block, add a resolutionStrategy (since there's no gradle plugin marker published) to resolve the plugin id, and then change the init.gradle's allprojects{apply} to apply by plugin id.

This allowed `:getStructure` to complete successfully.

* Gradle 8.0.2
* AGP 7.4.2
* 202 total modules count

Start by comparing docs/USAGE.md with the reported settings.gradle, build.gradle, and init.gradle setup, then reproduce :getStructure using Gradle 8.0.2 and AGP 7.4.2. Check the plugin behavior across Android and non-Android modules; done means the documented application completes without the reported evaluation or configuration errors.
