Fail artifact build if load and push are both false (#195)

If both are false, we get somewhat arcane failures. All existing
workflows set one to true and the other to false, this just enforces it.

Also, Fix a codespell issue that was introduced in 2.3.0 (previously
using 2.2.6).

Testing: Set both options to false in pr_build-
