Description

If you upload a WebP file as an animated emoji, attempting to download from CDN with the .gif extension raises 415 Unsupported Media Type, despite apparently being supported as per docs https://discord.com/developers/docs/reference#image-data - this does not occur the other way round, nor with other extensions.

Steps to Reproduce

1. Upload a WebP to a guild as an emoji - this is the example file I'm using.
2. Attempt to access it through https://cdn.discordapp.com/emojis/<emoji_id>.webp - as expected, this works fine/
3. Attempt to access it through https://cdn.discordapp.com/emojis/<emoji_id>.gif

Expected Behavior

It should return the emoji in .gif format, as per the CDN Endpoints section.

Current Behavior

It raises Error 415 / Unsupported Media Type - If this is intentional, this should be documented. It's somewhat of a pain because our library assumes all animated emojis can use the .gif extension, and there's no attribute denoting otherwise.
