• The httprouter version is invalid and is causing issues in Platform-go-sdk. Also, there's a newer version of uuid.

• Locking to go 1.21

• Pulling the executor from public go build image

You might want to mention in the PR title/description that you're also 1) locking the build to Go 1.21 (before, it was "latest") and 2) pulling that executor from Artifact Registry (instead of Quay.io).

This is a PUBLIC repo - is it appropriate that CI/CD is relying on internal images? Are you sure we need the sig-go-project context for this build?

If you were to use a public Go image, such as docker.io/library/golang:1.21, you may be able to remove the need for all internal/static secrets.

Done.

I'd suggest squashing ("fixup"ing) these commits into one before merging to keep the git history clean/readable.

Looks great!
