Typescript type for rawBody doesn't align with APIGatewayProxyEventBase body

The REQUEST.rawBody is the same as the lambda event body which should be string | null but is defined as string in the type definition.

https://github.com/jeremydaly/lambda-api/blob/main/index.d.ts#L146

Can it be updated to match? I'm happy to raise pull request.
