Finds all github_repository references in ./*.tf code not in Terraform state and imports them
Requires the github_repository identifiers in *.tf code to match the GitHub repo name, which does not work with repos which have dots in them eg. '.github'. Those rare exceptions must be imported manually.
Requires Terraform to be installed and configured
