[Feature Request] Making 'raw' requests inside request hooks

**What is your question?**
I wrote a little plug-in that adds a header to all my requests. The header value comes from another request that I have to make from the plug-in. So far I used a request library to do so, but I saw [in the docs](https://support.insomnia.rest/article/26-plugins#context.network) that there should be a network object in the context object and I would like to use it. But my context object has only app, data, request and store. This is basically what I would like to do:

```javascript
module.exports.requestHooks = [
async ctx => {
await ctx.network.sendRequest(...).then(...)
}
]
```

I couldn't find anything about the removal of this API in the changelog. Am I doing something wrong?

Start with the plugin documentation linked in the issue, especially the context.network section, then inspect how request hooks receive their context. Determine whether raw requests can be exposed through that context; done means the requested hook usage is supported or the limitation and intended alternative are clearly documented, with appropriate coverage identified.
