Snapshot Builds of Main are broken

[jhayes2-chwy]

PR #14027 has a build/gradle bug that is causing snapshots of the aws-sdk-1.11 library instrumentation to attempt to publish with version 1.12.80 instead of 2.18.0-ALPHA. This has been breaking snapshot builds of main ever since (~2 weeks).

Example error: https://github.com/open-telemetry/opentelemetry-java-instrumentation/actions/runs/15978529890/job/45069886431

* What went wrong:
Execution failed for task ':instrumentation:aws-sdk:aws-sdk-1.11:library:publishMavenPublicationToSonatypeRepository'.
> Failed to publish publication 'maven' to repository 'sonatype'
   > Could not PUT 'https://central.sonatype.com/repository/maven-snapshots/io/opentelemetry/instrumentation/opentelemetry-aws-sdk-1.11/1.12.80/opentelemetry-aws-sdk-1.11-1.12.80.jar'. Received status code 400 from server: Repository version policy: SNAPSHOT does not allow version: 1.12.80

In my fork I tested a trivial fix that adds the missing val to the version = ... expression, which fixes the issue as confirmed with a simple version-dumping task:

tasks.register("checkVersion") {
    doLast {
      println(project.version as String)
  }
}
