Publish to JSR package registry

[JoltCode]

Just stumbled across https://jsr.io/ - it's an interesting concept, should be easy to publish to there as well!

Took a quick look at this - basically you publish typescript code, and this handles the javascript transpile for you.

Then you install like pnpm install jsr:@hotosm/ui and it works like magic 👍
