vitest generator adds duplicate ^build to test target default dependsOn

[cogwirrel]

Current Behavior

When adding multiple typescript libraries with vitest, the generator keeps appending to dependsOn in the test target default, eg:

"targetDefaults": {
  ...
  "test": {
    "dependsOn": [
      "^build",
      "^build",
      "^build",
      "^build",
      "^build"
    ]
  },
}

This doesn't cause any issues, but it'd be nice not to keep appending the redundant entry :)

Expected Behavior

No duplicate dependency added.

Steps to Reproduce

1. Create a workspace (pnpm dlx create-nx-workspace)
2. Generate a ts library with vitest as the unitTestRunner (pnpm exec nx generate @nx/js:library --directory=lib1 --unitTestRunner=vitest --no-interactive)
3. Generate another (pnpm exec nx generate @nx/js:library --directory=lib2 --unitTestRunner=vitest --no-interactive)
4. Observe duplicate entry in nx.json
