Update CI and docs to use submodules for maiko/notecards/loops/test

doHCFILES.yml: replace 5 separate checkout steps with a single
  checkout using submodules:true; remove now-redundant .git cleanup step.

buildLoadup.yml: add submodules:true to Checkout Medley; remove
  separate Checkout Notecards + tar steps (notecards.tgz was already
  commented out of the release push).

make-gh-pages.md: replace manual clone+copy instructions with
  git clone --recurse-submodules; remove rm -rf of submodule dirs.
