Rollup alias.entries of array format should be handled

[zoeyzhao19]

Describe the feature

rollop alias option from build config file like

rollup: {
  alias: {
      entries: [
        {
          find: '@shared/types',
          replacement: path.resolve(projectRootDir, 'src/shared/types'),
        },
      ],
    }
}

entries above wouldn't get the right alias config since unbuild does not handle this scene. I have submitted a PR to improve it.
