Some downstream projects already define their desired Go version in their Dockerfiles, like:

• compose: https://github.com/docker/compose/blob/3975f021534e2c133c77434b74d22681feaa402b/Dockerfile#L18
• moby: https://github.com/moby/moby/blob/5512eea3d0bd2e4bcb1a34838b18b3b5f3de0edf/Dockerfile#L3

We could have some automation (cron-based GHA workflow would be probably enough) to automatically open PRs that update the docker-bake.hcl to match the Go version.
