Pull request overview

This PR normalizes Javaagent instrumentation package names for the internal Eclipse OSGi and OpenTelemetry Kotlin extension instrumentations so that their declared package aligns with the module/artifact naming and on-disk source layout (part of the broader package/module alignment effort in #18428).

Changes:

• Renamed the Kotlin extension instrumentation package from ...instrumentation.extensionkotlin.v1_0 to ...instrumentation.opentelemetry.extension.kotlin.v1_0.
• Renamed the internal Eclipse OSGi instrumentation package from ...instrumentation.internal.osgi to ...instrumentation.internal.eclipse.osgi.v3_6.
