fix: prevent coverage threshold failures in CI (#490)

This PR adds a step to the codecov workflow that resets all coverage
thresholds to empty objects before running tests. This ensures that the
codecov job never fails due to coverage thresholds not being met,
allowing it to simply collect and report coverage data to codecov.
