Pacts aren't cached during Gradle 'Test' tasks

[zromano]

When I run my junit tests, they produce pacts under builld/pacts/*.json. I'd expect that if I run ./gradlew --build-cache clean test twice in a row that my pacts would still be there when I pull the test task from the cache.

This currently doesn't happen unless I tell the test task to save the pacts as an output:

outputs.dir("${projectDir}/build/pact-tests")

Repro:

• Make a Java or Kotlin project with a pact test, Gradle Wrapper + Gradle 8.5, and au.com.dius.pact.consumer:junit5:4.6.7
• Use the ./gradlew --build-cache clean test command to test your project and generate the pacts under build/pacts
• Rerun the ./gradlew --build-cache clean test and expect your test results and pacts to be populated from the cache
• Note that everything is there except the pacts

Expectation:
I'd expect that pacts get cached by default when I use this dependency.

Additionally, if I specify a different output like so:

systemProperty("pact.rootDir", "${projectDir}/build/pact-tests")

I'd expect the results to still be cached by default.

At very least, I think this should be added to the docs
