Move all ESLint configuration to a centralized location at the root of the repo

[juliomenendez]

We should want all packages and tests to follow the same ESLint rules. Right now, there are ESLint configuration files all over the place. We should remove them and have a single one for the entire repository. If needed each package can customize small things, but in general I'd like the repository to follow a cohesive coding style.

Hi @juliomenendez!

I would like to work on this issue.

I noticed there is an automated PR from October, but the issue is still open and that the PR was closed without merge. I will consolidate the ESLint configurations into a single root config to ensure a cohesive coding style across all packages, but would definetely love more input on how you're vision is towards this, so it aligns with mine and I can contribute.

Can you assign it to me? Would love to contribute and work on this issue!

Happy coding!
