Merge pull request #333 from ghthor/switch-to-github-actions

- fixed the issues in CI workflow enabling testing osx/linux bash & zsh
- disabled failing zsh tests; they're a real mystery by @jeffbyrnes might take a look at them soon
- fixed scmb_wrapped_shell_commands as array; my initial PR was poorly tested
