第三方集服务集成Algolia站点配置缺少字段

[你好，经过测试，在添加Algolia搜索时，发现第三步配置缺少字段apiKey

还需要加上
apiKey: 'your api key'
站点完整配置为：
algolia:
applicationID: 'applicationID'
indexName: 'indexName'
apiKey: 'your api key'
chunkSize: 5000
感谢大神提供的主题，非常好用，thanks。

Review the documentation's Algolia setup instructions and locate the third-step site configuration example. Add the missing apiKey entry alongside applicationID, indexName, and chunkSize; the documentation is done when the complete configuration shown matches the example in the issue.

Written by the indexing model from the issue text.
