Fixed 'referrer' typo

[josephharkins]

Hm. I fixed a typo but it appears to be a typo in the actual language: https://en.wikipedia.org/wiki/HTTP_referer

But there is no note on the tutorial page and it mixes the different spellings, could lead to confusion (like me)

did a quick search too, found that's a known typo
maybe they decided to invent a new word to save one letter.

"HTTP REFERER", header as described
but
"document.referrer", prop that we use
so,
referrer.

Yeah, known glitch. Not only me who made this mistake! 🥳
