Correct Discord avatar code and add warning.

There's a mispelling which causes the avatar gathered to not be the desired size. Additionally, larger avatars appear to cause "Header too large" errors when users attempt to access services (at least for me via a proxy providers.) This can also be seen users have a very large JWT in their request headers. (You can use https://github.com/traefik/whoami for debugging). Signed-off-by: Aterfax <[email protected]>
