Feature request: Create docstring for a function (like Insert Roxygen Skeleton)

[Mkranj]

in the Edit pane. Similar to Rstudio's "Insert Roxygen Skeleton", I'd love to see that replicated for R code, and a similar docstring being created for Python code.
The syntax to be used (R or Python) could be gleaned from the current file extension.

We do have this available for R! It is a code action and you can see how to use it in the video in #1744 (comment).

I opened #10522 to track us adding similar functionality for Python.
