There's a race condition in the h2_bundle.go of go 1.16.10 and later. The
issue https://github.com/golang/go/issues/51799 mentions that this might
be fixed in go 1.19, so we'll need to wait for that.
We make sure we build our docker images with go 1.16.9 to not run into
the issue in the wild.
We add a GitHub workflow that is triggered whenever a new version tag is
pushed. It will trigger a docker image build for that version and
automatically push it to the specified repo.
