feat: add react and vue chainlink templates

[fabioDMFerreira]

The templates read chainlink price feeds.

Hey! Thanks a lot for your contribution.

I'm in the middle of an overhaul for CEA v2, which will make this PR obsolete. But v2 will make it much, much easier for contributors like you to build templates for CEA.

Do you feel this is urgent, and I should merge it in, or would you be happy to wait a little bit? ETA is currently mid of Sep.

Hi @PaulRBerg. I leave that decision to you.

I'm planning to add the chainlink templates for create-eth-app v2. If the v1 will be discontinued, maybe it doesn't make sense to merge this code.

I'm planning to add the chainlink templates for create-eth-app v2.

Great. That will be much easier to do, and maintain!

[fabioDMFerreira]

Hi @PaulRBerg. Any updates about the v2?

[PaulRBerg]

Hey @fabioDMFerreira, I got side-tracked with other projects and life-goals in the meantime ..

Happy to re-open this if you'd be so kind to rebase from the latest commit on main and apply any changes that may be necessary.

[fabioDMFerreira]

@PaulRBerg I've rebased and fixed the linting issues. Please review.

@fabioDMFerreira looks like you didn't give me permission to contribute to your fork.

I have made some other changes in the meantime and we have to rebase again - sorry!
