is_remix is no longer accepted

What changed

Usually ignored rather than rejected, so the call succeeds and does something subtly different.

Affects is_remix on MessageAttachmentRequest reachable from 8 operations. Grep for it: nothing else will tell you.

Who is affected

Code that sends Discord's MessageAttachmentRequest objects, used by 8 Discord operations.

Before and after

Code that breaks

await client.post("/…", {
  // is_remix is now ignored, not rejected
  is_remix: value,
});

Based on Discord’s published API specification. How severity is decided.
