Gradle plugin: findProperty causes "Project <x> cannot dynamically look up a property in the parent project" when Isolated Projects enabled

[3flex]

Describe the bug
Using Gradle's Isolated Projects mode flags an issue caused by this plugin.

dokka uses findProperty to check whether the org.jetbrains.dokka.experimental.tryK2 property has been enabled or not. This is problematic as one of its behaviours is to "Search up through this project's ancestor projects" which causes the IP violation.

Expected behaviour
It should be possible to use dokka with Isolated Projects enabled.

Screenshots

To Reproduce

1. Checkout https://github.com/detekt/detekt
2. Run ./gradlew build -Dorg.gradle.unsafe.isolated-projects=true

Dokka configuration
Run dokka with Gradle runner with org.jetbrains.dokka.experimental.tryK2 property unset.

Installation

• Operating system: Windows
• Build tool: Gradle v8.8
• Dokka version: 1.9.20

Additional context
Possibly dokka support should be added & tracked in YouTrack under https://youtrack.jetbrains.com/issue/KT-64575.

A fix is likely as simple as using gradleProperty instead on Gradle 6.2 and up.
