WIP: Feature/update react 18 + improvements

[jeffdrumgod]

I'm working on a project with react 18 and I decided to update the project for that. I reviewed all the tests.

I'm still testing it, but I'll leave this PR (with WIP) in case anyone wants to help or use it.

And in case you consider receiving this PR, it's here :)

Or if you want to indicate something that needs to change or that you disagree with, I'm at your disposal too.

Focus on update:

• React 18
• Work on Node 18
• Change tests to Vitest
• Small improvements
• ✏️ WIP (update examples - fix small bugs/warnings)
