Bugfix: Exit on programmatic apply

[eyecatchup]

This PR closes #99, which reports that the cli process fails to exit when applying a template. This is true when running in programmatic mode.

The root cause is that the last commit (#aa0dda7, #83) removed the ux.exit(0) call after the 'Template applied successfully.' log message within the runProgrammatic function — well, in fact, the line was commented out rather than deleted.

For reference, runInteractive ends with

      log.warn(BSL_LICENSE_HEADLINE)
      log.info(BSL_LICENSE_TEXT)
      log.info(BSL_LICENSE_CTA)

      ux.stdout('Template applied successfully.')
      ux.exit(0)

Whereas runProgrammatic ends with

    ux.stdout('Template applied successfully.')

    // Hide BSL license info if running programatically for now
    // log.warn(BSL_LICENSE_HEADLINE)
    // log.info(BSL_LICENSE_TEXT)
    // log.info(BSL_LICENSE_CTA)
    // ux.exit(0)

Before the change, runProgrammatic ended with

    ux.info('Template applied successfully.')
    ux.exit(0)

It seems more than likely that commenting out ux.exit(0) was unintentional while updating the console logs. Maybe @bryantgillespie, who did that change, could take a quick look and potentially merge this and release a fixed version to restore the proper exit behavior in CI environments. 🤞
