Subject: [PATCH] fix: use image/jpeg as the target format

when using the Chrome's native ImageCapture it outputs a JPEG. Default [`HTMLCanvasElement.toBlob()`](https://developer.mozilla.org/en-US/docs/Web/API/HTMLCanvasElement/toBlob) outputs a `png` unless otherwise specified.
This change aligns those two implementations.
