Rename remaining javaagent instrumentation packages to versioned paths

[Copilot]

Several javaagent modules still used unversioned or inconsistent package paths relative to their module version. This PR moves those packages to version-scoped paths within their owning modules and updates every repository reference that embeds the old names.

• Renamed package roots

  • akka-http-10.0 → io.opentelemetry.javaagent.instrumentation.akkahttp.v10_0
  • camel-2.20 → io.opentelemetry.javaagent.instrumentation.camel.v2_20
  • kotlinx-coroutines-1.0 → io.opentelemetry.javaagent.instrumentation.kotlinxcoroutines.v1_0
  • opentelemetry-extension-annotations-1.0 → io.opentelemetry.javaagent.instrumentation.extensionannotations.v1_0
  • opentelemetry-extension-kotlin-1.0 → io.opentelemetry.javaagent.instrumentation.extensionkotlin.v1_0
  • opentelemetry-instrumentation-annotations-1.16 → io.opentelemetry.javaagent.instrumentation.instrumentationannotations.v1_16
  • play-mvc-2.4 → io.opentelemetry.javaagent.instrumentation.playmvc.v2_4
  • play-mvc-2.6 → io.opentelemetry.javaagent.instrumentation.playmvc.v2_6

• Directory moves

  • Moves were done with git mv inside each module so package layout matches the new namespace.
  • Nested subpackages moved with the versioned root in one pass, e.g. Akka client, server, and server.route, Camel decorators, and coroutines instrumentationannotations.

• Repository-wide reference updates

  • Updated package, import, and FQCN references across Java, Kotlin, Scala, Groovy, resources, service descriptors, properties/yaml, and docs.
  • This includes places that embed slash-based package paths in resource files and generated/package-check inputs.

• Collision cleanup

  • Applied the kotlinx-coroutines-1.0 rename before opentelemetry-instrumentation-annotations-1.16 so the top-level instrumentationannotations package became unambiguous.
  • Also moved the remaining coroutines test package path under v1_0 to keep the module fully aligned.

// before
package io.opentelemetry.javaagent.instrumentation.akkahttp.client;

// after
package io.opentelemetry.javaagent.instrumentation.akkahttp.v10_0.client;

@copilot fix CI

Fixed by 88648b8. I checked the failing CI logs and the stale WithSpanSingletons import in WithSpanInstrumentation was the breakage; the branch now passes the targeted package-name check and affected module compiles.

@copilot resolve the merge conflicts in this pull request

Resolved in 2b59933 by merging the latest main into this branch. The branch is clean and the targeted package-name/compile validation passed afterwards.
