React-email render not working on Safari due to 'ReadableByteStreamController not defined'

[Ildrid]

Describe the Bug

The render function does not return neither data or error when using Safari/mac. Console error states 'ReadableByteStreamController not defined'.

Solved this in our project by implementing "web-streams-polyfill/polyfill".

@naaa760 Feel free to open a PR. I'd advise you go through this for dev workflow.

To fix this kind of issue, we probably are going to have to include some sort of polyfill in the render function itself. So part of looking into fixing this is researching and trying to understand if we should really include a polyfill, or if it would be better to advise users to include it themselves.
