Code Review

This pull request updates the Go version used in the Cloud Build test step from 1.24 to 1.25. While this is a straightforward dependency update, it introduces an inconsistency in the Go versions used across the project. The test environment will now use Go 1.25, but the application build environment (defined in the Dockerfile) remains on Go 1.20, and the go.mod file specifies Go 1.19. To ensure consistency and prevent potential issues, I've recommended updating the Go versions in the Dockerfile and go.mod file to match the one used for testing.

[gemini-code-assist]

This change updates the Go version for the test step to 1.25, but other parts of the project are using older Go versions. This can lead to inconsistencies and hard-to-debug issues.

Specifically:

• The Dockerfile used for building the application binary (see golang-sample/Dockerfile:18) is still on golang:1.20-buster. It's best practice to test and build your application with the same version of Go.
• The go.mod file (golang-sample/go.mod:3) specifies go 1.19. It's recommended to update the go directive to match the version of the Go toolchain you are using.

Please consider updating these other files to use Go 1.25 for consistency across your development, testing, and build environments.
