Implement UI testing in create fuels

[danielbate]

create fuels aims to provide a full stack and feature complete solution for working with and deploying dApps on fuel.

We should provide a UI testing solution so that consumers test their frontend applications. We should use something like playwright or vitest to integrate with our own infra.

Terminoplogy-wise, perhaps this could be called ui tests.

I expanded on this thought here.
