fix: add optional platform data to nodes (PL-000) (#353)

<!-- You can erase any parts of this template not applicable to your Pull Request. -->

**Fixes or implements PL-000**

### Brief description. What is this change?
I noticed in voiceflow/general-service#384 we were casting many nodes:
`} as GoogleNode.Capture.Node;`
`} as GoogleNode.Interaction.Node;`

using `as` is usual not the best pattern and we should want to define the type so everything is expected.

I looked everywhere where we write `platform: context.platform,`
