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.

Beginne in makeFsImporter.ts und verfolge, wie nicht aufgelöste Dateien unter node_modules gelesen und geparst werden. Prüfe die bestehende Behandlung rund um resolvedSource und parseCache und verifiziere anschließend, dass installierte Pakete, die .d.ts-Dateien bereitstellen, die erwarteten Schnittstelleninformationen in den Component-Props liefern.
