add local search with plugin @easyops-cn/docusaurus-search-local

Fix #666

Currently we are using algolia to implement the search feature across the whole website, but for some unknown reason, the search is broken, there is no any results showed in the result page.

This PR refer to docusaurus community recommended plugin @easyops-cn/docusaurus-search-local to implmenet the search feature, the result looks pretty good, and it is a local search engine, no 3rd party service needed for this feature. Seems like a good option for open source community.

LGTM

Thanks for the fix! It looks good, and let's see how it works online.

One more thing: could we use the official docusaurus-search-local after it supports zh language? Because I think the zh language support will be merged to the upstream in the future.

Good job btw!

I think it should work when we have zh support, let's see how it goes, I am glad to make it work for zh if wechaty docs supports zh and the search broken.

Seems like search in zh works well with this plugin.
