[RangeSlider] Thumbs are not accessible to UiAutomator2

Description: The thumbs of the RangeSlider are no longer accessible in the view tree used by UiAutomator2

Expected behavior: The thumbs should appear in the view tree available to UiAutomator2 so that automated tests can continue to manipulate sliders.

Source code:
I narrowed it down to the changes in https://github.com/material-components/material-components-android/commit/ab52e6afc4a80c3adc9536a58831fe7883667871

  @Override
  public void onInitializeAccessibilityNodeInfo(AccessibilityNodeInfo info) {
    super.onInitializeAccessibilityNodeInfo(info);
    // Setting visible to user to false prevents duplicate announcements by making only our virtual
    // view accessible, not the parent container.
    info.setVisibleToUser(false);
  }

Android API version: N/A

Material Library version: 1.13.0

Device: Pixel 8 Pro

Workaround:
We can create our own RangeSlider and override onInitializeAccessibilityNodeInfo to info.setVisibleToUser(true).

Start by reviewing commit ab52e6afc4a80c3adc9536a58831fe7883667871 and locating RangeSlider's onInitializeAccessibilityNodeInfo implementation. Reproduce the UiAutomator2 view-tree behavior, then add or update coverage for the thumbs. Done means RangeSlider thumbs appear in the UiAutomator2 tree and remain usable for automated slider manipulation.
