Outdated jcenter() call for Android

[35rod]

Describe the issue

For some reason, the build.gradle for Android uses jcenter()...which has been deprecated for quite some time now.

Here is the log:

A problem occurred evaluating project ':square_in_app_payments'.
> Could not find method jcenter() for arguments [] on repository container of type org.gradle.api.internal.artifacts.dsl.DefaultRepositoryHandler.

* Exception is:
org.gradle.api.GradleScriptException: A problem occurred evaluating project ':square_in_app_payments'.
Caused by: org.gradle.internal.metaobject.AbstractDynamicObject$CustomMessageMissingMethodException: Could not find method jcenter() for arguments [] on repository container of type org.gradle.api.internal.artifacts.dsl.DefaultRepositoryHandler.

Additional context

I'm pretty sure replacing it with mavenCentral() can be used to solve the problem, but it would be nice to see it in an official update so I don't have to manually replace it each time on different computers. :)
