Current page item on Android w/ Talkback is not navigable with swipe navigation

# 🐛 Bug Report

Swiping through a page the current page within a breadcrumb does not participate in the swipe sequence so a user can never read it. It also does not get read when you tap it.

## 🤔 Expected Behavior

It should appear in both swipe sequence and when you do tap to read on the screen.

## 😯 Current Behavior

Go to https://react-spectrum.adobe.com/react-spectrum/Breadcrumbs.html on Android with talkback running. swipe through to the current page breadcrumb item and observe that it is skipped

## 💁 Possible Solution

It seems that a role="link" which is not focusable gets skipped. Adding tabindex=-1 to the link resolves the issue. The link is disabled so -1 should work fine.
