Nested <Text>'s with a render function don't render

**Describe the bug**
https://react-pdf.org/components#text states that
`Text supports nesting of other Text or Link components to create inline styling.`
but nesting Text with a render function does not render the text at all.
This worked in 3.x previously, if that helps.

**To Reproduce**
```
const Test = () => (



This does not render} />


"This does not render"} />

This does render} />

This does render} />



);

ReactPDF.render();
```

**Expected behavior**
Nested Texts are expected to render when using a render function.

**Why do we want to nest Texts in the first place?**
We have textboxes with arbitrary content which can also be variables that are interpolated on generation. Within a Textblock there should be flow and one of the variables is `pageNumber`, where we need to use a render function to get the number. Now a `pageNumber` can be within a paragraph which should be a `` element to enable inline flowing.
