Enhance the DocSearch(Algolia) by adding all URLs from our website to for indexing.

[huan]

We are using the Algolia service for supporting our open source project Wechaty.

• Optionally customize the look and feel by following the DocSearch documentation (See https://docsearch.algolia.com/docs/styling/)
• You can also check your configuration in our GitHub repository (See https://github.com/algolia/docsearch-configs/blob/master/configs/wechaty.json).

Currently, the index only contains the pages start from the URL /docs. It will be great if we could to enhance the settings to index all URLs (articles) from our wechaty.js.org website.
