vitest for generator fails only when using nx test in freshly generated workspace

[parker-norwood]

Current Behavior

npm config get registry in @nx/js's setupVerdaccio() throws an error in vitest tests only when running with nx.

Expected Behavior

Running vitest with nx doesn't cause tests to fail when they pass when executed with vitest directly.

Steps to Reproduce

# 1. Generate a barebones ts workspace.
npx create-nx-workspace@latest org --preset ts --ci skip --formatter prettier && cd org/
# 2. Add @nx/plugin plugin
npx nx add @nx/plugin
# 3. Generate a plugin.
npx nx generate @nx/plugin:plugin --directory=tools/ --importPath=@org/tools --linter=eslint --name=tools --unitTestRunner=vitest --no-interactive
# 4. Generate a generator in the plugin.
npx nx generate @nx/plugin:generator --path=tools/src/generators/example/example --name=example --unitTestRunner=vitest --no-interactive
# 5. Extend the built-in @nx/js generator in this newly created generator.
# Example: https://nx.dev/extending-nx/recipes/local-generators

// tools/src/generators/example/example.ts
export async function exampleGenerator(
  tree: Tree,
  options: ExampleGeneratorSchema
) {
  const projectRoot = `packages/${options.name}`;
  libraryGenerator(tree, {
    directory: projectRoot,
    publishable: true,
    importPath: `@org/${options.name}`,
  });
  generateFiles(tree, path.join(__dirname, 'files'), projectRoot, options);
  await formatFiles(tree);
}

# 6. Run vitest, showing that the tests pass.
npx vitest run
