actions-hugo feat: Validate checksum

async function sha256(str) {
  // Convert string to ArrayBuffer
  const buff = new Uint8Array([].map.call(str, (c) => c.charCodeAt(0))).buffer;
  // Calculate digest
  const digest = await crypto.subtle.digest('SHA-256', buff);
  // Convert ArrayBuffer to hex string
  // (from: https://stackoverflow.com/a/40031979)
  return [].map.call(new Uint8Array(digest), x => ('00' + x.toString(16)).slice(-2)).join('');
}

  const digest = await sha256("hello");
