fix: remove incorrect dbasunag/opendatahub-tests submission (ambient-code#321)

PR ambient-code#301 submitted an assessment for dbasunag's fork instead of the
official opendatahub-io/opendatahub-tests repository. The correct
submission was made in PR ambient-code#314.

This removes the incorrect submission to avoid duplicate/confusing
entries in the leaderboard.
