add RStudio to editors/IDEs (#604)

Hello, this is my first PR here, so please let me know if there are any mistakes.
I'm adding RStudio to the list. It is the most widely used IDE for the R language for statistics/data science. Its developer, [Posit](https://posit.co/), has pivoted to AI very hard. I added a minimum set of examples here, but can expand if needed, as their website is covered in hype for AI coding.
