Types from `*.d.ts` files are not parsed in node_modules

If an installed package would deliver type informations with d.ts files, it won't parse these files and interface informations are missing in the props.

It could be fixed in the makeFsImporter.ts file with a simple addition:

if (!nextFile) {
      // Customization: try to read from a "d.ts" file instead, if it exists
      if (resolvedSource.includes("node_modules")) {
        const dtsPath = resolvedSource.replace(".js", ".d.ts");
        if (fs.existsSync(dtsPath)) {
          resolvedSource = dtsPath;
        }
      }
      // Customization: end

      // Read and parse the code
      const src = fs.readFileSync(resolvedSource, "utf8");

      nextFile = file.parse(src, resolvedSource);

      parseCache.set(resolvedSource, nextFile);
}

But i didn't want to make another pull request because i'm not sure if this is a nice way to solve it.

Inizia da makeFsImporter.ts e segui il modo in cui i file non risolti sotto node_modules vengono letti e analizzati. Controlla la gestione esistente relativa a resolvedSource e parseCache, quindi verifica che i pacchetti installati che espongono file .d.ts producano le informazioni sull’interfaccia previste nelle props dei componenti.
