PM-18129

📔 Objective

• Adds illustration for the Authenticator on the 2fa screen.
• Corrects some logic so only the Yubi key image is below the description (prior to this change there was only 2 images so just flipped the boolean a bit to make it work generically).
• Updates image size to match figma for email and authenticator images on that screen.
