Maven release docs (#1087)
Maven release docs (#1087)

Summary:
*Context: The Yoga OSS build has not been given a lot of attention over the past couple of years and is in serious disrepair. I'll try to get the release pipeline going again to publish to Maven Central as JCenter is shutting down. A bunch of intermediate commits may still have broken builds but will be inching closer to a working one.*

Adds some docs on how to use the release workflow.
