Remove Bintray repository to speed up Android builds

[HorusGoul]

Details

I ran into long build times when developing some changes for the Android native part of the app (+30 minutes long builds!) and thought this made no sense.

I found out that the culprit was the Bintray repository, and removing it from the list of repositories is what solved the issue.

Why is the Bintray repository the cause? JFrog closed it!, and they wanted to close JCenter too. However, they say they'll keep that one as a read-only repository indefinitely.

I tried replacing jcenter with mavenCentral, but there are still some packages that we use and haven't migrated (for example, Flipper or some internal dependencies of react-native). We'll need to keep an eye on that in the future.

Tests/QA Steps

Run the following commands and make sure the app gets built in a reasonable amount of time:

cd android
./gradlew clean
cd ..
npx react-native run-android
