pixi integration with RStudio server

Make R and its dependencies available in RStudio server using pixi thanks to a wrapper for rsession, which detects if pixi is there, and set the environmental variables accordingly: NINAnor/template-r#12 (comment).

Hey @frafra - no one on our team is a heavy R user but I'd hope that someone in the R community can help figure this out!

Thanks! I mean, I think I solved it, and I wanted to share my solution :)

Excellent! I did not get that from your message but maybe I didn't read carefully enough, hehe!
