Add type definitions for *.svx files by default

Currently, MDsveX doesn’t provide a way for TypeScript to really understand *.svx files. The way Svelte deals with this issue is by declaring a global ambient module (in their ambient.d.ts file. Since *.svx files from what I can tell are just disguised Svelte components, this is what I’m using currently to workaround the IDE errors I’m getting:

global.d.ts

// Based on svelte/runtime/ambient.d.ts
declare module "*.svx" {
    export { SvelteComponentDev as default } from "svelte/internal";
}

But it’d be awesome if this could be included in the mdsvex package or something to not require this sort of thing. Thanks!
