Normalize external annotations javaagent package name

[trask]

Part of

• Tracking package and module name alignment #18428

[Copilot]

Pull request overview

This PR normalizes the external-annotations javaagent instrumentation package name by renaming the legacy io.opentelemetry.javaagent.instrumentation.extannotations package to io.opentelemetry.javaagent.instrumentation.external.annotations, and updates all test/config references accordingly (aligned with the broader package/module alignment effort in #18428).

Changes:

• Renamed javaagent (main + test) packages from ...extannotations to ...external.annotations.
• Updated declarative config YAML test resources to reference the new fully-qualified test class names.
• Updated Gradle test JVM args that reference the test classes in config properties.
