[Tabs] Aria-Hidden used in JS is tripping accessibility checkers

When using the code to incorporate tabs on a webpage, **aria-hidden="true"** is causing accessibility flags. It appears to be in the JS as it's not hard-coded into the HTML or CSS. Since the ah-true is pretty much never needed, is it necessary here, or is there a way around its usage? Otherwise, the design is great and excellent to use.

Inspect the JavaScript that assembles the Tabs component and reproduce the accessibility checker flags caused by aria-hidden="true". Determine whether the attribute is necessary for the tab behavior, then verify that the tabs still work and the accessibility warnings are resolved.
