Enhance and Organize Example Prompts for Different Control Types

[MMcola]

Description

The project mentions the existence of prompt examples in the README (Prompt examples for different models can be found in the [prompt_exampeles](resources/demos/prompts_examples.md)), but this file might not be complete or well-organized to showcase the capabilities of different control types supported by RelaCtrl.

Impact

Without clear, organized prompt examples:

1. Users may not understand how to properly format prompts for different control types
2. The full capabilities of the model remain unclear
3. It's difficult to reproduce results from the paper or website

Proposed Solution

1. Create a well-organized prompt examples documentation with:
   • Separate sections for each control type (Canny, Style, etc.)
   • Example image + prompt + result triplets for each control type
   • Guidelines for prompt formatting specific to each control type
   • Parameter recommendations for optimal results
2. Include a table summarizing the different control types and their use cases
3. Fix the typo in the README (change "prompt_exampeles" to "prompt_examples")
4. Provide example scripts that demonstrate how to run inference with each control type
