#### Background
This is the task to add native support for GPay into the Android Wikipedia App in partnership with fr-tech. Adding Native payment method support was one of the proposed enhancements identified for improving donor experience in the apps. Fr-tech and the iOS team have already added support for ApplePay. Adding support for Google / Apple Pay was also a [[ https://meta.wikimedia.org/wiki/Community_Wishlist_Survey_2022/Mobile_and_apps#Accepting_donations_from_mobile_apps | request in the 2022 Wishlist ]].
#### Requirements
- Entry points for flow: 1) From the "Donate" option in settings 2) from an in-app banner
- An option to pay via GPay should be presented when tapping Donate
- The GooglePay option or any branding should not be visible if the user doesn't have GooglePay set-up or is restricted for compliance reasons. In this case, the user should be sent directly to donate.wikimedia.org
- Tapping "Donate with GPay" should launch the Payment Authorization view controller/action sheet
- Tapping "Other payment method" should launch the existing link used in the app to donate.wikimedia.org
