Component used: Navigation, Safe Args plugin

Version used: 2.3.4

Hi!

I'm working on creating a debug view for AppSearch as a Jetpack library. I'm using Navigation component for managing switching between fragments. I'm using the Safe Args plugin for passing in arguments to a destination fragment. However, the classes the Safe Args plugin generates in the build tree are causing the Jetpack API lint check to fail:

> Task :appsearch:appsearch-debug-view:generateApi

../../../../out/androidx/appsearch/appsearch-debug-view/build/generated/source/navigation-args/release/androidx/appsearch/debugview/view/DocumentFragmentArgs.java:119: error: Builder must be final: androidx.appsearch.debugview.view.DocumentFragmentArgs.Builder [StaticFinalBuilder]

../../../../out/androidx/appsearch/appsearch-debug-view/build/generated/source/navigation-args/release/androidx/appsearch/debugview/view/DocumentFragmentArgs.java:123: error: Missing nullability o    Your change has API lint issues. Fix the code according to the messages above.

    If a check is broken, suppress it in code in Kotlin with @Suppress("id")/@get:Suppress("id")
    and in Java with @SuppressWarnings("id") and file bug to
    https://issuetracker.google.com/issues/new?component=739152&template=1344623

    If you are doing a refactoring or suppression above does not work, use ./gradlew updateApiLintBaseline

The class generating these errors is attached. I would appreciate it if the Lint issues could be resolved so I can continue using Safe Args!
