fix(node/crypto): Assign publicKey and privateKey with let instead of const

[birkskyum]

Because public/private key are reassigned, they should be let instead of const.

  const privateKey = new PrivateKeyObject(privateKeyHandle);  // <- Const here
  const publicKey = new PublicKeyObject(publicKeyHandle); // <- Const here

  if (typeof options === "object" && options !== null) {
    const { publicKeyEncoding, privateKeyEncoding } = options as any;


    if (publicKeyEncoding) {
      publicKey = publicKey.export(publicKeyEncoding); // <- Reassigned here
    }

    if (privateKeyEncoding) {
      privateKey = privateKey.export(privateKeyEncoding);  // <- Reassigned here
    }
  }

This gives an error:

ERROR Assignment to constant variable.

CI failed because I gave wrong PR title initially. I expect it to pass if rerun.
