Pull request overview

Adds a declarative OpenTelemetry SDK configuration file for the smoke-tests/netty-test app, wires it into the Gradle run task via -Dotel.config.file, and bumps the default solarwinds-otel-sdk version used by the test to exercise newer SDK functionality (including CEL-based sampling config).

Changes:

• Added smoke-tests/netty-test/sdk-config.yaml with resource, SolarWinds distribution settings, OTLP exporter, and sampler configuration.
• Updated smoke-tests/netty-test/build.gradle.kts to bump the default SDK version and pass -Dotel.config.file=sdk-config.yaml to the app.
