Code Review

This pull request aims to upgrade the Golang version in the Dockerfile for security reasons. However, a medium-severity vulnerability has been identified because the suggested version golang:1.26rc3 is a release candidate, which is not stable and can introduce instabilities or security risks. It is recommended to use a recent stable version of Golang, such as 1.22, instead.

[gemini-code-assist]

The Dockerfile is currently using golang:1.26rc3, a release candidate (RC) version. Using RC versions introduces unnecessary risk as they are not stable and may contain unpatched bugs or security vulnerabilities. It is strongly recommended to use a stable, generally available (GA) version of Golang, such as golang:1.22, to ensure build stability and security.
