Fixes #6675

What is the reason for them to be served from media.discordapp.net instead of the usual cdn.discordapp.com btw.

@JustinBeckwith hmm should we even have stickers in that CDN table if they aren't at the CDN base URL? if we wanna keep in table i think the callout should move up to the Image Base Url section or within an asterisk callout under the table

I think this call out is specific to GIF stickers - but I defer to @jkcailteux here

All stickers are technically in the CDN so its probably right to keep that there. Although i can see why its confusing since you can't access GIF stickers that way...

We have to do some stuff via cloudflare workers to get our media proxy to work with GIFs in this situation (without it, theres no point in even supporting GIFs for stickers), so we have to route the request through mediaproxy and have the worker look into the CDN.

I think adding a comment like Justin has done here is probably fine, I'm not sure how else to make this less confusing, other than specifying the base url for every sticker type in its own section or something

Oh my beloved cloudflare..
OK fair, thanks for the insight

Apparently, some CDN URL such as avatars are already transparently routed through the media proxy despite being accessed on cdn.discordapp.com.
Example: https://cdn.discordapp.com/avatars/643945264868098049/c6a249645d46209f337279cd2ca998c7.png?size=16 (size parameter work here).

Maybe you can do something similar for GIF stickers when accessed over cdn.discordapp.com?
