LGTM, can you also bump the go version used in the build & release logic in the GitHub actions so that we don't run into trouble when we do a release:

2 instances here to change 1.14 -> 1.15 - https://github.com/solo-io/wasm/blob/master/.github/workflows/release.yaml#L16-L19

Also codegen here - https://github.com/solo-io/wasm/blob/master/.github/workflows/pull_request.yaml#L21

done
