Add Roboflow Workflows (#73)

* Add Roboflow Workflows

Adds Roboflow Workflows to the awesome-openrouter list. The OpenRouter
block lets Workflows users run any of 300+ vision-language models on
images and detection crops with their own OpenRouter API key.

* Use official Roboflow logomark for logo

Replaces the GitHub org avatar with Roboflow's brand-purple logomark,
downscaled to 256x256.
