docs: walletconnect, rainbowkit integration

[rube-de]

Description:

The current documentation lacks comprehensive instructions for integrating WalletConnect and RainbowKit into the frontend to ensure compatibility with the Sapphire. This omission hinders developer adoption and slows down the development process for applications leveraging the Sapphire. Refer to the Blockvote app for an existing implementation.

Expected Docs:

Clear and concise documentation detailing the specific steps, configurations, and potential challenges involved in integrating WalletConnect and RainbowKit with the Sapphire. This should include:

• Specific network configurations required for Sapphire.
• Code examples demonstrating the integration process.
• Troubleshooting tips for common issues.

Recommendations:

• Create a dedicated documentation section: Develop a specific section within the existing documentation outlining the integration process for WalletConnect and RainbowKit with Sapphire.
• Provide code examples: Include practical code snippets demonstrating the correct implementation.
• Address potential issues: Document common errors and their solutions.
• Cross-reference existing implementations: Link to the Blockvote app as a working example.
