Use hardhat verify instead of hardhat etherscan-verify on yarn verify

[damianmarti]

hardhat verify has more features, like linking to libraries.

Hello mates,

TLDR:

I didn't know hardhat-etherscan plugin depreciated, so I'm prooving below that why we need to move hardhat-verify, lol 😄

---

We can yarn verify successfully on polygonMumbai, sepolia etc.
However, we're unable to do the same in polygonZkEvmTestnet, arbitriumNova, scrollSepolia etc. networks.
This is something outside of the API keys issue as you may notice the error message is different.

---

What might be the reason?

I learned that hardhat-etherscan supports the below list.
After reviewing it you'll better understand why the same contract verification

• ✅ works on arbitriumGoerli
• 🚫 but doesn't work for arbitrumSepolia and, others such as:
  • polygonZkEvm, polygonZkEvmTestnet, zkSync, zkSyncTestnet, base, baseGoerli, scroll, scrollSepolia
    • they don't overlap with the list of hardhat-etherscan therefore it returns the error

---

Anyway, if you are busy, I'm happy to take over this task to complete on my free time, @damianmarti and @austintgriffith

Yes, sure! Thanks!!

Today, I was able to verify two contracts on scrollSepolia and polygonZkEvmTestnet as an example with hardhat-verify. I learned quite a lot and below are the links of the contracts:

• sepolia.scrollscan.com/address/0xfdd6...
• testnet-zkevm.polygonscan.com/address/0xdd85...

However, I noticed it requires quite a lot to update in existing libraries in order to use hardhat-verify therefore, I'll create the PR after having some housekeeping
