Update README.md for ReadKit (#4710)

* Update README.md

I use ReadKit (free version) on iOS and macOS. 

Pro purchase is required to manage feeds, which I don't agree with given that we're using FreshRSS. Managing local feeds I can understand that could be value add.

* Tested + details

* Re-order based on capabilities
