Update bip-0141.mediawiki

The byte representation of "<0 <32-byte-hash>>" is "0x220020{32-byte-hash}"

What was listed here would be the byte representation of "0 <32-byte-hash>". The text explains that there is only one item in scriptSig, so I'm guessing the byte representation is wrong. Also the corrected byte representation would produce the same sig/pubkey described in P2WSH after following the bip16 rules.
