- Do not render a source handle for the leaf nodes
- Upgrade the `@xyflow/react` library

## Other options considered
React Flow exposes a hook to get the connections of the current node. I
tried to use this hook – which makes things way simpler – but I couldn't
find a way to make it work in Storybook. I had two options: 1. Set up
React Flow to render the nodes properly, 2. Mock the hook in Storybook.
The first option was hard to achieve as the `<Reactflow />` component
renders a whole flow, and it doesn't play well with the idea of
rendering a single node in a story.
The second option seemed overkill as mocking modules with Storybook is
not straightforward. See
https://storybook.js.org/docs/writing-stories/mocking-data-and-modules/mocking-modules.
I chose to keep the initial version of my code, written before I spot a
function simplifying the code. We can give it a look another time.
