Configuration caching problem

[plnice]

Steps to reproduce:

1. Attach plugin (tested version 0.4) to the project that is based on Gradle 7.3.3 and has org.gradle.unsafe.configuration-cache=true in gradle.properties
2. Run ./gradlew snyk-test
3. Gradle reports configuration caching problem:

- Task `:snyk-check-binary` of type `io.snyk.gradle.plugin.SnykBinaryTask`: invocation of 'Task.project' at execution time is unsupported.
  See https://docs.gradle.org/7.3.3/userguide/configuration_cache.html#config_cache:requirements:use_project_during_execution
