@typescript/ata JSR registry support

I understand this is not a critical issue. I've already tried to make some changes and open a PR but I think the issue might need some more thought put in.

I was trying to figure out a way to be able to allow imports of JSR packages in the monaco editor.

@typescript/ata relies on jsdelivr so the JSR packages aren't available there.

Issues I've encountered

1. Not clear how imports should work. In Deno it's possible to do it like this:

import { something } from 'jsr:@scope/package';

For Node, (https://jsr.io/docs/npm-compatibility), it's necessary to add a new registry https://npm.jsr.io/ and the name of the package gets transformed to

import {} from '@jsr/scope__package'

or packages.json can be updated like this:

 // package.json
 {
   "type": "module",
   "dependencies": {
-    "@jsr/luca__cases": "1"
+    "@luca/cases": "npm:@jsr/luca__cases@1"
   }
 }

2. Where to import the files from

Initially I tried querying jsr.io directly: https://jsr.io/@luca/flag/meta.json
based on https://jsr.io/docs/api

Then I figured it'd be better to use the npm compatibility layer so I get well formed ESM instead of Typescript.
I've used things like https://npm.jsr.io/@jsr/tscu__dependent

The issue now is that I don't get access to specific files, but to a tarball of a specific version.

At this point it's not clear what solution should be correct.
I figured maybe I'll open a discussion on this.

Inizia esaminando @typescript/ata e il modo in cui attualmente risolve gli import tramite jsdelivr. Confronta l’API dei metadati di JSR con i tarball di compatibilità di npm, usando come requisiti gli esempi di import di Deno e Node presenti nell’issue. Il lavoro sarà considerato completato quando sarà stato concordato e implementato un approccio chiaro per gli import JSR e la risoluzione dei file in Monaco.
