Fix Pest coverage conflict in GitHub Actions workflow

Remove --coverage flag from test execution command to fix conflict
with --coverage-clover flag. Using both flags together caused Pest
to fail with "Coverage not found in path" error. The --coverage-clover
flag alone is sufficient for generating the XML coverage report needed
by Codecov.
