Update documentation with a disclaimer about node v18 ( experimental ) and v21 (stable) supporting fetch API #209
Description
Hello @lquixada,
First thank you so much for this library.
With node 21 supporting already fetch API (stable) and 18 ( experimental ) should we create a disclaimer that in the repository about not needing to install cross-fetch for those use cases ?
This would save people from increasing their bundle size if they are in a most recent node version.
Maybe even a warning if installed in those runtimes could be an interesting feature.
What do you think about this ?
