incompatitble with configuration cache on Gradle 8.4

[WhosNickDoglio]

I tried integrating focus into a project using Gradle 8.4 with configuration cache enabled and got a warning regarding incompatibilities.

I've updated the sample project to Gradle 8.4 and enabled configuration cache as a reproducer and this is the warning I got:

3 problems were found storing the configuration cache, 1 of which seems unique.
- Task `:sample:createFocusSettings` of type `com.dropbox.focus.CreateFocusSettingsTask`: invocation of ‘Task.project’ at execution time is unsupported.
  See https://docs.gradle.org/8.4/userguide/configuration_cache.html#config_cache:requirements:use_project_during_execution

PR with reproducer:#41

Lol just now noticing CreateFocusSettingsTask is marked as not compatible with configuration cache.

Yeah, it's inherently not compatible with config caching because it works by resolving a projects dependencies, which it can't do from the cache.
