Release v0.20.0

[MrAlias]

Note: this does not release the auto/sdk pacakge. The interdependence with the auto package means that additional work is needed if we plan to release these simultaneously. This additional work should not block the beta release of the auto package given the auto/sdk package contains only minor dependency updates and un-exported code clean up.

Overview

This release is the first beta release of the OpenTelemetry Go Auto-Instrumentation project.

Changed
