Update interactive session 2a #28
Description
We currently show students two routes to creating version controlled repos:
(1) Interactive session 2a currently introduces GitHub by asking students to convert a local repo into a remote repo using usethis::use_git and usethis::use_github.
(2) Interactive session 3b shows students how to create a remote repo on GH and clone into a local repo.
Flipping the order would be better because the remote --> local is more intuitive and less prone to error (or entirely losing the local -- > remote).
