Increase sticker upload limit

[Bluenix2]

Summary

The upload limit for stickers is incredibly tiny, 500 KB for an APNG file is nothing. For reference, emojis have a limit of 256 KB but can only be up to 128x128 in size.

I am scrambling trying to make the file less than 500 KB whilst also making sure that it looks relatively good considering how it will be viewed. Is this limit set as to encourage Lottie images?

They said they will probably stop allowing lottie files from being uploaded as stickers so I doubt it.
