🐛 Bug Report: File preview webp output doesn't work

[Andree98]

👟 Reproduction steps

I'm calling the file preview endpoint with output=webp argument to get an image in webp format but in the response the image comes in the jpeg format

• The original format of the image stored in the bucket is jpeg
• The image stored in the bucket is smaller than 10MB
• Including image/* and image/webp accept header in the request doesn't change the outcome *Edit: Including an 'image/webp accept header in the request works but only if the image isn't cached on appwrite
• The file preview endpoint is being called from the flutter sdk

👍 Expected behavior

The preview endpoint response should be an image/webp

👎 Actual Behavior

The preview endpoint response is image/jpeg

@Andree98, thanks for raising this issue from our Discord discussion! 🙏🏼 I'll have to play around with this some more to see what's going on.

The problem seems to be Appwrite will only send webp images if the request contains an image/webp accept header, which is not the case for some SDKs.
