Forc init with example

[SilentCicero]

The Forc toolchain should provide a few example starter projects at the init stage which are easily accessible. This allows for a more seamless getting started experience.

The basic one would be the Counter example, eventually more complex examples like a Uniswap or Token could be added.

For now, we should work to add in a Counter example at the init (as it demonstrates state, testing and a basic smart contract). As the Fuel architecture grows with indexers, having basic examples like this will go a long way to show how everything fits together.

forc init --counter-example

Eventually it could be a drop down.

forc init

  [x] An empty project
  [ ] Counter
  [ ] Uniswap
