Push a custom version of Stable Diffusion 3

What this post added

This post details the process of pushing a custom version of Stable Diffusion 3 (SD3) to Replicate. It outlines the prerequisites (Git, Docker, Replicate account), the steps to create a model on Replicate, install Cog, clone the `cog-stable-diffusion-3` repository, and finally push the model using `cog push`. It also suggests iteration ideas such as adding inpainting support, an upscaler, or modifying the prediction interface.
