Check for existence of SSH folder and create it if it does not exist before writing the keys to it

Package Merge Request

Package Changes

Previously, the k3d-dev.sh script assumed that the user's SSH folder existed. On a new machine where SSH has not yet been used, this is not the case. The updates to the script check to see if the folder exists and will create the folder if it does not.

Closes 2766
