Hi! Dhaiwat from Ankr here. First of all, I'm a fan of these templates. Thanks for maintaining them!

I saw that there could be some value added to these templates by adding Ankr's Free Public RPCs. They're free, don't require sign-ups and serve millions of requests every day reliably.

I think it would make a lot of sense to add these public RPCs to the readme and the hardhat config as fallbacks or defaults. Do you want me to go ahead and create a PR for that? Lmk what you think, thanks! :)
