Previously, AVIF images were not converted to other file types as
expected, despite `upload.formatOptions` specifying a different file
type.
The issue was due to `canResizeImage` not recognizing `'image/avif',`
causing `fileSupportsResize` to return `false` and preventing the image
from undergoing format conversion.
This fix updates `canResizeImage` to include `'image/avif'`, ensuring
that AVIF images are processed correctly and converted to a different
file type when specified in `formatOptions`.
