[Feature] dependencies task for locks

In lieu of a solution to https://github.com/gradle/gradle/issues/19081 which references my ticket... could we get a task that is just for dependencies? maybe `spotlessDependencies` then I could simply add it to my root `dependencies` task. I admit to this being a workaround, but I don't like running `spotlessApply --write-locks` running the formatter or a check seems bad.
