Revisiting from release failure in internal JS-6275

This dependency was added when build and publish smithy-ts step had failed in aws-sdk-js-v3

A problem was found with the configuration of task ':smithy-typescript-codegen:sourcesJar' (type 'Jar').
  - Gradle detected a problem with the following location: '/tmp/smithy-typescript-1d003498c9c145ba44fa8c51b25eec629f65a940/smithy-typescript-codegen/build/generated/resources'.
    
    Reason: Task ':smithy-typescript-codegen:sourcesJar' uses this output of task ':smithy-typescript-codegen:set-dependency-versions' without declaring an explicit or implicit dependency. This can lead to incorrect results being produced, depending on what order the tasks are executed.
    
    Possible solutions:
      1. Declare task ':smithy-typescript-codegen:set-dependency-versions' as an input of ':smithy-typescript-codegen:sourcesJar'.
      2. Declare an explicit dependency on ':smithy-typescript-codegen:set-dependency-versions' from ':smithy-typescript-codegen:sourcesJar' using Task#dependsOn.
      3. Declare an explicit dependency on ':smithy-typescript-codegen:set-dependency-versions' from ':smithy-typescript-codegen:sourcesJar' using Task#mustRunAfter.
    
    For more information, please refer to https://docs.gradle.org/9.0.0/userguide/validation_problems.html#implicit_dependency in the Gradle documentation.
