[Feature] dependencies task for locks

[caleb-cushing0-kr]

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.

PR's welcome! Pseudocode for what would work:

List<Integer> hashCodes = new ArrayList<>();
for (FormatterStep step : steps) {
    hashCodes.add(step.hashCode()); // calculating hashcode forces the dependencies to resolve
}

You can grab all the formatter steps which matter here
