chore: drop unused serviceaccount issuer config for removed www oidc endpoint

[xnoto]

The service-account-issuer.yaml block pointed k3s at the www-hosted static OIDC issuer (https://makeitwork.cloud/oidc) for the unbuilt AWS STS web-identity design. The endpoint had zero consumers and is being removed from www.

No live impact: cloud-init applies only at VM provision time, so the running k3s VM is untouched; and the apiserver validates ServiceAccount tokens with its local key, so even future provisions behave identically (k3s default issuer) without this block.
