_Add convenience initializer for `LambdaRuntime` to accept
`LambdaHandler` instances with `Void` output_

### Motivation:

Following PR #581, which added convenience initializers for
`LambdaRuntime` to accept `LambdaHandler` instances with `Encodable`
outputs, there was still a gap for handlers that return `Void`. This is
useful, for example, for AWS event sources like SQS, where the
`AWSLambdaEvents` package provides `SQSEvent` but there's no
corresponding output type - handlers simply process messages and return
`Void`.

Without this initializer, developers had to manually wrap their handlers
with `LambdaCodableAdapter` and `LambdaHandlerAdapter`, which was
verbose and inconsistent with the new API (similar to what is described
in #581)

### Modifications:

1. Added a new `init(decoder:handler:)` convenience initializer to
`LambdaCodableAdapter` in `Lambda+JSON.swift` that accepts a
`JSONDecoder` for handlers with `Void` output.

2. Added a new convenience initializer to `LambdaRuntime` that accepts a
`LambdaHandler` instance with `Void` output directly, handling the
wrapping internally.

3. Updated documentation comments to distinguish between handlers with
`Void` and `Encodable` outputs.

### Result:

Developers can now initialize `LambdaRuntime` with handlers that return
`Void` using a clean, direct API. This is especially useful for event
sources like SQS:

```swift
import AWSLambdaEvents

struct MySQSHandler: LambdaHandler {
    func handle(_ event: SQSEvent, context: LambdaContext) async throws {
        // Process SQS messages
    }
}

let runtime = LambdaRuntime(lambdaHandler: MySQSHandler())
```

This provides API completeness, matching the convenience initializers
for handlers with `Encodable` outputs, and delivers better ergonomics
for common serverless patterns.
