Setting yarn.downloadBaseUrl = null got deprecated in KGP 2.1.
It instructs to use yarn.downloadBaseUrlProperty instead, but that is internal.
😕

Ah, the deprecation hint is just wrong: https://youtrack.jetbrains.com/issue/KT-77326

Found this while wanting to disable self-managed yarn (preferring to use system yarn), here's the updated snippet for root `build.gradle.kts`:

rootProject.plugins.withType<YarnPlugin> {
    rootProject.the<YarnRootEnvSpec>().download = false
}
