Version 1.50.0

This release targets the OpenTelemetry Java Instrumentation 2.20.1.

Note: This release broadly applies some style guidelines across the repository. As a result, some classes that were visible might be package/private. Other non-final classes may now be final. See #2182 and #2210 and #2212 and #2213 for examples and details. These changes are not expected to break anyone, so please open an issue if this causes problems.
