New webpage Read Streams example is confusing

[yoavain]

Enter your suggestions in details:

Lines 3-4 of the "Read Streams" example are confusing.
I suggest extracting them into a new "Fetch" example.

I see! That's indeed confusing because the Read Streams shows two different examples.

Feel free to make a PR removing the first fetch part, but if possible, find a way to make the example still last 11 lines. (We're aiming for every example to be 11 lines to keep the CodeBox consistent)
