Use new language selector

[chrisvire]

One of the teams in SIL has created a new language selector.

Here is a demo:
https://sillsdev.github.io/EthnoLib/?path=/story/demos-dialogdemo--primary

Here is the architecture:
https://github.com/sillsdev/EthnoLib/blob/main/README.md

Dependencies:
https://github.com/sillsdev/EthnoLib/blob/main/components/language-chooser/common/find-language/package.json

From discussion:

There are three layers:

1. Search Logic: @ethnolib/find-language
2. Headless React Logic @ethnolib/language-chooser-react-hook
3. Material UI Interface @ethnolib/Mui Language Chooser
   So you can reuse whatever layer, and hopefully add alternatives, e.g. on layer 2, we could have a "Headless Svelte" or whatever.

I haven't looked much into "headless Svelte". With Scriptoria, we would want to style it with Tailwind/DaisyUI.

We would want to add the Svelte layer to the EthnoLib repository and use it from S2 (feature/svelte branch).

I have challenged @gmjgeek to try to work on the EthnoLib code. I don't know how much time he will have.

Garret Jones is working on the EthnoLib library to support Svelte (sillsdev/EthnoLib#87) and vanilla state management (sillsdev/EthnoLib#113)
