Adding support for Thai text segmentation

[mattleff]

First off, thanks for a great library! 🙏🏻

I'm wanting to use Pagefind in a project that has Thai text and I'm interested in adding support for Thai in Pagefind. I see that Charabia has a Thai segmenter (meilisearch/charabia#114). Can you give me some pointers toward what I'd need to do to enable Thai segmentation in Pagefind?

Ah, good note! (Sorry for the delay).

We'll need to enable the thai feature for charabia, and then configure that language as an extended language in Pagefind.

I can make sure to include this in the next release!
