Add import templates

This creates a couple of initial templates in line with what
Melanie & I have been testing. I figure it will save re-creating on
live & also help us to test in future

Also included is a sample data file for us to use while testing

Includes civicrm/civicrm-core#26046
and civicrm/civicrm-core#26055

Bug: T303986
