Fix for grids without comprehensive infotexts

Edited in fix in Github editor and mistyped from local copy

When generating grids, some scripts such as img2img loopback and ultimate SD upscale do not pass infotexts for each image since they are the same prompt.

If you attempt to save those images using the saved button in the UI it will fail because it will look for the selected image info text. This fixes those errors by replicating the infotext for as many images are passed into the image list if the infotext parameter is none.

Fix method 1 : pin Setuptools==69.5.1

Fix bug where under some circumstances an extra "." was inserted between the file base name and the file extension.
The bug is triggered when the extension argument is one of "jpg", "jpeg", or "webp", and the image exceeds the format's dimension limit. Then the extension variable is set to ".png", resulting in the fullfn variable to evaluate to a string ending with "..png".

* Consistent with implementations in k-diffusion.
* Makes this compatible with https://github.com/AUTOMATIC1111/stable-diffusion-webui/pull/15823

* Include both SDXL and SD 1.5 variants (https://research.nvidia.com/labs/toronto-ai/AlignYourSteps/howto.html)
