Use node:buffer explicitly (#835)

While it works without explicit
[`node:buffer`](https://github.com/nodejs/node/blob/main/doc/api/buffer.md)
in a Node.js environment, it won't work in environments compatible with
Node.js. There's no downside to explicitly using `node:buffer`. This
change supports that.
