Use utils.IterateOrderedMap() as intended, via for:=range (require Go 1.23)

Future!

While this looks good at a first glance, I would like to wait some weeks before bumping the Go version. Allowing each of us to get to the latest Go version in their pace, before hitting build failures.

Dev's platforms w/ Go 1.23

• NixOS (@oxzi) https://search.nixos.org/packages?channel=unstable&show=go&from=0&size=50&sort=relevance&type=packages&query=go
• Ubuntu (@Jan-Schuppik @jrauh01, I guess) https://packages.ubuntu.com/search?keywords=golang-go&searchon=names&suite=noble&section=all
• Arch (@julianbrost)
• brew (everyone else)

Thanks for the roadmap. Just for your information, Go 1.23 is already available in the nixpkgs, just not under the go package name, as this would result a massive rebuild. The go package will be bumped for the next staging thing, iirc.

Please remove the change to the go.mod and rebase.

The rebase I requested is required to get this running. I have rebased this PR for you and would merge it unless the CI is going to fail now.
