[Bug]: Not support PNG file parse

[xjxl520303]

When use PNG file in Figure's imge, like the follow code:

#figure(
  image("附件/24.png", width: 50%),
  caption: [
    图片描述文字。
  ]
)

report ERROR:

Error: failed to decode image (Format error decoding Png: Invalid PNG signature.)

But works well in vs code with same image file.
