Configuring tasksToInstrumentPredicate does not work as documented

[wilkinsona]

Describe the bug
The documentation shows the following example for configuring the predicate:

tasksToInstrumentPredicate = t -> true

Adapting this to disable instrumentation by returning false does not work.

To Reproduce
Steps to reproduce the behavior:

plugins {
	id 'java'
	id 'org.graalvm.buildtools.native' version '0.9.13'
}

repositories {
	mavenCentral()
}

graalvmNative {
	agent {
		tasksToInstrumentPredicate = t -> false
	}
}

$ gradle test
[native-image-plugin] Instrumenting task with the native-image-agent: test

Expected behavior
Returning false for all tasks disables instrumentation for all tasks.

System Info (please complete the following information):

• OS: N/A
• GraalVM Version: N/A
• Java Version: N/A
• Plugin version: 0.9.13
• Gradle version: 7.5.1

Additional context
It works, i.e. the log message about task instrumentation disappears, when specifically using a Predicate:

graalvmNative {
	agent {
		java.util.function.Predicate<Test> predicate = { t -> false }
		tasksToInstrumentPredicate = predicate
	}
}

This may be a duplicate of #301. Sorry if it is. However, I don't think that would explain (to me anyway) why the behavior is different depending on how the predicate is declared.
