PIL requires a string format name, whereas `Format.PNG` is an "enum string" which is not quite the same type. I had not noticed this problem because I had manually tested the test on a VM where the cached Stable Diffusion XL Docker image was from before this change. Tested on a fresh VM with a freshly-built Docker image now. This is split in two changes because the image needs to be rebuilt. The first change updates the image, and the second change re-enables the test. PiperOrigin-RevId: 618874414
