Release v3.0.1

Java SDK 3.0.1 is a patch release for the SDK, testing library, OpenTelemetry plugin, and Durable Execution Telemetry Exporter.

Fixes

• Preserve callback failures that provide an error type without a message. The exception and telemetry now retain the type without adding : null or an empty suffix, including after replay (#851).
• Report the stored original error type in OpenTelemetry operation exception events, including errors from other languages. The throwable message and stack diagnostics are preserved (#860).
• Build Maven artifacts using the release commit timestamp (#842).

This release also updates AWS SDK dependencies and expands compatibility and suspended-child telemetry coverage.
