Coinbase-Android-sdk URL pointing issue on developers.coinbase.com

[derekdunes]

On https://developers.coinbase.com/docs/wallet/coinbase-connect/mobile; the Coinbase-android-sdk link points to an archived library on github.com (https://github.com/coinbase/coinbase-Android-sdkURL). This makes it hard for new Android developers reading the documentation to find this repo. Please update the link to this repo to save us hours of searching to get to this repo. Thanks
