Scaffolding IaC should install `solana-dev-skill`

When `surfpool start` is executing on a new project for the first time, Surfpool is scaffolding some IaC.
When the scaffold code path is executing, we should include the following command (non blocking, fire and forget style):
```bash
npx -y skills add https://github.com/solana-foundation/solana-dev-skill --skill "*" -y
```
