Contributions summary:Yoshi primarily focused on migrating existing Go-based services (shippingservice, checkoutservice, and productcatalogservice) from the `dep` package management system to Go modules. This involved removing `dep` related files, adding `go.mod` and `go.sum` files, and upgrading OpenTelemetry dependencies. Additionally, the user updated Dockerfiles to utilize Go modules. This work streamlines dependency management and improves the build process for the cloud-ops-sandbox project.
