Update examples to latest version of effect

[eddiecooro]

Hello there! :wave:

As someone relatively new to FP, I've been diving into effect-ts.

After going through the "effect time" videos and reading all the materials I could find, I turned to the examples here. My aim was to discover a suitable starting point to build a mini-application. However, I noticed the examples were quite different from what I saw in the videos. It was a bit challenging, especially for a newcomer like me, but I eventually realized that effect-ts/* is quite different from the examples in this repo. It seems we're using @effect/* more now.

I understand you're working on improving the documentation. I'm not certain about the timeline for its completion, but I'd like to suggest a potential enhancement. What about adding a brief disclaimer to the Readme section of the effect project? Nothing too detailed, just a short heads up for anyone just starting out with the library, to understand the relationship between this project and the @effect-ts/core library.

Another piece of feedback I have is about updating these examples to align with the latest @effect/io package. I've seen some changes, and the starter example doesn't seem helpful as it's still on 0.1.1.
I'm open to helping with this myself. I just wanted to check in first to see if this aligns with your plans or if this repo is being phased out and will be detached from the main effect repo.
