Add Documentation for Verifying Smart Contracts Using Foundry Script on Rootstock

[jerydam]

Is your feature request related to a problem with the content or with the docs platform? Please describe.
The Rootstock Developers Portal provides excellent guides on deploying and testing smart contracts using Foundry (e.g., Deploy Smart Contract and Test ). However, there is no specific documentation on verifying smart contracts on the Rootstock network using a Foundry script. Developers are often frustrated when they deploy contracts but cannot easily verify the source code on the Rootstock Explorer, which is critical for transparency and trust in decentralized applications (dApps).

Describe the solution you'd like
I’d like a new guide in the Rootstock Developers Portal under the "Smart Contracts" section, titled "Verify Smart Contract Using Foundry Script." The guide should:

Explain how to use Foundry’s forge verify-contract command to verify a smart contract on the Rootstock Testnet and Mainnet.
Provide a sample Foundry script (e.g., in script/Verify.s.sol) that automates verification using the Rootstock Explorer API.
Include steps to configure the Foundry project with the Rootstock Explorer API key and RPC URLs (e.g., https://public-node.testnet.rsk.co for Testnet).
Show how to handle common verification errors, such as mismatched bytecode or incorrect constructor arguments.
Reference the Rootstock Explorer for checking verification status.

This guide would complement existing Foundry-related content and the deployment guide.

Describe alternatives you've considered

Using Hardhat Verification Plugin: The portal already covers verifying contracts with Hardhat (e.g., Verify a Smart Contract using the Hardhat Verification Plugin. However, Foundry is preferred by many developers for its speed and advanced testing features, so a Foundry-specific guide would be valuable.
Using Remix IDE: Remix supports verification, but it’s less scriptable and integrated compared to Foundry’s CLI-based workflow.
