Lesson3 some nitpicks still needed to lesson content:

Changes (needed) and some observations before I forget

• [x] Some changes need to be done regarding the breaking changes from new upgrades of ethers.js and Hardhat Toolbox dependencies
• [ ] Might be a good idea to add two more MATIC faucet possibilities (some 'suppliers' are expecting real ETH in a dev's wallet to avoid spam - the joys of inclusivity)
• [ ] should add a mention about different handling of baseURI in comparison to lesson2
• [ ] should also mention explicitly that we handle env variables differently to lesson2 and why.
• [ ] should add something about the nature of import/require statements in the scripts files (need to check lesson2 for how that was described)
• [ ] in the very last Checkpoint question, a 'correct [true] answer' states that .env files 'ensures easy collaboration among devs' - is that correct?
• [ ] Q4 and Q5 are pretty much the same in the final quiz.

@wolovim if you plan to return to lesson 3, can you have a skim over these? I had forgotten about them tbh
