Scores a correct answer with a sigmoid over confidence probability:
`1 / (1 + exp(-steepness * (probability - midpoint)))`.

# `t`

```elixir
@type t() :: %GEPA.Adapters.Confidence.Scoring.Sigmoid{
  midpoint: float(),
  steepness: float()
}
```

# `describe`

# `new`

```elixir
@spec new(keyword() | map()) :: t()
```

# `score`
