Plugin requires Java 15

Kotlin 1.7.20
Android Gradle Plugin 7.3.1
Gradle 7.5.1

I have built the plugin to the local Maven repository and modified my project's main `build.gradle.kts` like this:
```
buildscript {
repositories {
mavenLocal()
google()
mavenCentral()
}
dependencies {
classpath("com.android.gradle.replicator:project-replicator:0.2")
classpath(libs.kotlin.pluginGradle)
classpath(libs.android.pluginGradle)
}
}

allprojects {
repositories {
google()
mavenCentral()

apply {
plugin("com.android.gradle.replicator.ProjectReplicatorPlugin")
}

tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile::class) {
kotlinOptions.jvmTarget = JavaVersion.VERSION_11.toString()
}
}
```

However when syncing Gradle I get the following error:
```
> Could not determine the dependencies of null.
> Could not resolve all task dependencies for configuration ':classpath'.
> Could not resolve com.android.gradle.replicator:project-replicator:0.2.
Required by:
project :
> No matching variant of com.android.gradle.replicator:project-replicator:0.2 was found. The consumer was configured to find a runtime of a library compatible with Java 11, packaged as a jar, and its dependencies declared externally, as well as attribute 'org.gradle.plugin.api-version' with value '7.5.1' but:
- Variant 'apiElements' capability com.android.gradle.replicator:project-replicator:0.2 declares a library, packaged as a jar, and its dependencies declared externally:
- Incompatible because this component declares an API of a component compatible with Java 15 and the consumer needed a runtime of a component compatible with Java 11
- Other compatible attribute:
- Doesn't say anything about org.gradle.plugin.api-version (required '7.5.1')
- Variant 'runtimeElements' capability com.android.gradle.replicator:project-replicator:0.2 declares a runtime of a library, packaged as a jar, and its dependencies declared externally:
- Incompatible because this component declares a component compatible with Java 15 and the consumer needed a component compatible with Java 11
- Other compatible attribute:
- Doesn't say anything about org.gradle.plugin.api-version (required '7.5.1')
```

Reproduce the Gradle sync using the shown Kotlin 1.7.20, Android Gradle Plugin 7.3.1, Gradle 7.5.1, and Java 11 setup with the locally published project-replicator:0.2 plugin. Inspect the plugin's build configuration and published variant metadata to determine why it requires Java 15; done means the compatibility behavior is resolved or the Java requirement is explicitly documented.
