Issue description

In https://github.com/E3SM-Project/zppy/blob/main/tests/integration/template_directions.md, the line rm -rf #expand user_www#forsyth/zppy_test_bundles_www/<UNIQUE ID>/v2.LR.historical_0201/image_check_failures erroneously includes "forsyth". That should be removed.

The same error appears for the complete-run test line.

Actually the change should be:

# Remove the image check failures, so they don't end up in the expected files.
rm -rf /lcrc/group/e3sm/public_html/diagnostic_output/ac.forsyth2/forsyth/zppy_test_complete_run_www/<UNIQUE ID>/v2.LR.historical_0201/image_check_failures

=>

# Remove the image check failures, so they don't end up in the expected files.
rm -rf image_check_failures_complete_run

This change also needs to be done for bundles.
