Provides a way to make requests
npm install @smithy/fetch-http-handler

This is the default requestHandler used for browser applications.
Since Node.js introduced experimental Web Streams API in v16.5.0 and made it stable in v21.0.0,
you can consider using fetch-http-handler in Node.js, although it's not recommended.
For the Node.js default requestHandler implementation, see instead@smithy/node-http-handler.
