VOL-4836 - Cosmetic edits to trigger a jenkins job.

Makefile
makefiles/
----------
  o Added targets help, lint, sterile, todo, {go,java,python}-all.
  o replace "rm -rf" with make builtin $(RM) -r.
  o make clean: pass --no-run-if-empty to avoid a failure condition.

tox.ini
-------
  o Test target runs cleanly with python v3.10.6 so include as a valid interpreter version.

python/
python/test/
------------
  o Cosmetic edit, update copyright notice to trigger a jenkins job.
