SDK configuration pull request

Purpose of this PR

During Typespec Migration for the API Specs, enable-sync-stack property for the Java SDK was turned to false. This is causing invalid SDK generation from Typespec. This PR corrects it

• Make changes to the SDK configuration only when there are no modifications to the API specification, eliminating the need for an ARM or Stewardship Board API review.
