Some project-related tweaks

The project is great and after using it for a while I made some tweaks and changes.

Hope it helps.

• chore: upgrade golang to 1.21 #79
  • Update project runtime and project dependencies to resolve security scanning vulnerabilities

  • Update the version, adjust the build method to make the build more efficient, and use stable container versions to make the build results more stable.
