[BUG] github ci not able to clone tpl over ssh

[j-d-carmichael]

This test: src/tests/openapiNodegen_git.ts

In GH CI it cannot clone the tpl repo over ssh due to missing keys - out of CI the tests pass just fine.

The following attempts have been made to try and get it working:
Adding ssh keys via keygen

      - name: 'ssh keys generate'
        run: ssh-keygen -t rsa -q -f "$HOME/.ssh/id_rsa" -N ""
