vendor: the GREASE ECH body the comment claims is the one the codec makes

Browse source 
`client/ech.rs`'s comment said the greased body is "185 to 281 bytes" while the
codec computes `32 * (4 + rand % 4) + 16` tag plus a 42-byte header — 186, 218,
250 or 282 — which is also what this repository's own shape doc
(`fingerprint/shapes/mod.rs`) says. The comment was the odd one out.

Fixed in the vendored source and in `PATCH.diff` together, because the two have to
agree for the patch to reproduce the tree. Same character count on the line, so no
hunk offset shifts. The codec is untouched.
