Daily Test Coverage Improver - Fix Vitest Coverage Command

[github-actions]

Issue

The coverage-steps action.yml was using an incorrect Vitest flag --coverageDirectory which is not supported by Vitest 4.x. This caused the coverage tests to fail during execution.

Fix

Removed the --coverageDirectory=coverage flag from both React and backend.ai-ui test commands. The coverage directory configuration is already properly set in the vitest.config.ts files for both projects:

coverage: {
  provider: 'v8',
  reporter: ['text', 'json', 'json-summary', 'html'],
  reportsDirectory: 'coverage',  // ← Already configured
  // ...
}

Changes

• Removed --coverageDirectory=coverage from React tests command
• Removed --coverageDirectory=coverage from backend.ai-ui tests command

Testing

The fix has been committed and ready for testing in CI.

What Happens Next

Once this PR is merged, the coverage steps should execute successfully and Phase 3 of the Daily Test Coverage Improver workflow will be able to proceed with actual test coverage improvements.
