Could not get unknown property 'source' for generate-proto-generateDebugProto of type

These are 2 errors that I've faced on [Working with Proto DataStore](https://developer.android.com/codelabs/android-proto-datastore#4):
`Could not get unknown property 'source' for generate-proto-generateDebugProto of type`
and
`error: Unresolved reference: protoc`

On gradle-8.11.1 and kotlin-gradle.

Here is the resolve:

In build.gradle instead of previous protobuf version:
```
protobuf {
protoc {
//the version here should be the same as what you have in your app build.gradle
artifact = "com.google.protobuf:protoc:3.18.0"
}

generateProtoTasks {
all().configureEach {
builtins {
create("java") {
option("lite")
}
}
}
}
}
java {
sourceCompatibility = JavaVersion.VERSION_1_8
targetCompatibility = JavaVersion.VERSION_1_8
}
```
And in build.gradle project level:
```
plugins {
//...
id("com.google.protobuf") version "0.9.5" apply false
}
```
The rest remains the same.

Reproduce the codelab's Proto DataStore setup from the linked step using Gradle 8.11.1 and the Kotlin Gradle plugin. Inspect the app build.gradle and project-level build.gradle entries shown in the issue, then verify that Gradle sync and the proto generation task complete without the reported errors.
