Title

Add Tutorial on Zero-Knowledge Proofs with Noir for Rootstock dApps

Description

This contribution adds a comprehensive tutorial to the Rootstock Developer Portal under the /docs/tutorials section, titled "Zero Knowledge Proofs on Rootstock with Noir." The purpose is to educate developers on using ZK proofs and the Noir language to build privacy-focused dApps on Rootstock, enhancing user confidentiality. It addresses the need for practical guides on advanced cryptographic techniques, featuring:

• Explanations of ZK proofs and Noir's role in creating ZK circuits.
• A step-by-step demo for a "Secret NFT Club" dApp, where users prove knowledge of a secret code to mint an NFT without revealing it.
• Critical analysis of benefits, limitations, and Rootstock's Bitcoin-secured verification.
  Changes include a new Markdown file (/docs/tutorials/zk-proofs-noir.md) with front matter (title, description, tags, sidebar_label, sidebar_position), adhering to the style guide. No existing issues are resolved, but this enhances the portal's developer resources.

Screenshots/GIFs

N/A (No visual UI changes; the contribution is a documentation file. Code snippets and explanations are included in the Markdown for clarity.)

Testing

• Ran yarn build to verify the build process, ensuring no broken links or Markdown errors in the new tutorial file.
• Checked sidebar navigation and search metadata (title, tags, description) locally using yarn start to confirm the tutorial appears correctly in /tutorials and is findable via Algolia search.
• Validated code snippets (Noir, Solidity, JavaScript) by running them in a local Hardhat environment forked from Rootstock testnet, confirming the demo dApp's functionality.
• Ensured compliance with front matter requirements and style guide (e.g., absolute links, no special characters in titles).

Checklist

• I have read and understood the contributing guidelines.
• I have followed the style guide and formatting guidelines.
• I have added appropriate comments to explain the changes.
• I have tested my changes thoroughly.
