Missing close call on blob-get-stream causes the stream to never finish reading

I believe blog get stream algorithm is missing a call to close that stream, which results in consumers of that readable stream never 'finishing' reading that stream.

For example, without a call to "close", from my reading 'done' will never get set to true for the following test:

let buffer = new ArrayBuffer(200);
let bytesReceived = 0;
let offset = 0;

let blob = new Blob(['Data to be read! 🦬']);

const stream = blob.stream();
const reader = stream.getReader({ mode: "byob" });

while (true) {
  let result = await reader.read(new type(buffer, offset, buffer.byteLength - offset));

  if (result.done) {
    return;
  }

  buffer = result.value.buffer;
  offset += result.value.byteLength;
  bytesReceived += result.value.byteLength;
}

I think the fix should be just adding a close into the blob-get-stream algorithm after all bytes have been queued into the stream.

Start with the File API blob-get-stream algorithm and the Streams specification's ReadableStream close algorithm. Reproduce the supplied Blob.stream() BYOB-reader example and verify that reading eventually returns done=true after all bytes are queued.
