Remove gradle push task

[matinzd]

Hi guys,
Do we even need this task to be applied to the main project? I think it's better to remove it.

lottie-react-native/src/android/build.gradle

Line 6 in ca013ac

apply from: 'gradle-maven-push.gradle'

Causing this issue: #919

Yeah agree, let's do that when the android fabric work lands 👍
