Move all Android Video SDK Releases to MavenCentral

[Alton09]

Due to the upcoming sunsetting of Bintray, we are in the process of moving all of the existingvideo-android and video-android-ktx aar release artifacts to Maven Central. New releases will also be published to Maven Central. Once this work is complete this issue will be closed.

Just a note, com.twilio:video-android:6.2.1 depends on com.getkeepsafe.relinker:relinker:1.3.1 which is available only from jcenter. It is not yet available from mavenCentral.

Ah yes so we moved all of the SDK artifacts over to MavenCentral. This version contains a relinker dependency that is hosted on MavenCentral. Apologies, forgot to close this ticket as part of the release process.
