Use different search library

[neilboyd]

Chirpy uses Simple-Jekyll-Search. This supposedly has a feature to allow search with exact match, but it doesn't seem to be working, and the latest version (Chirpy gets 1.10.0 from a CDN) doesn't seem to have that code (I debugged in Chrome dev tools). I asked the developer of Simple-Jekyll-Search about this and he suggested that it's easy to write my own javascript rather than using a library. Here are some suggestions:

• https://cri.dev/posts/2020-02-08-Simplest-Vanilla-JavaScript-static-site-blog-search-for-Jekyll,-Hugo,-11.ty-eleventy/
• https://cri.dev/posts/2021-04-06-simple-static-site-blog-search-javascript-client/
• https://cri.dev/posts/2022-04-07-web-workers-search-index-blog-search/

Although his suggestions also don't have exact search.

Maybe it's easier to just include the latest version of Simple-Jekyll-Search directly in my site instead of using the one from Chirpy. I did that in #57
