Update mockups displaying former NYT onion site

Context

There's an Android mockup displaying the New York Times' onion site currently being used in many places, however, there isn't a NYT onion site anymore. So we need to update these mockups and replace their onion site screenshots.

Reference

Places that need update

Use the Tor Browser Releases file as a staging ground for this work:

• New "Tor Browser for Android" download page
• Google Play Store

Feel free to add more places to the checklist.
