[FEAT]: Add multilingual support for ocr mudule

### What would you like to see?

Currently, OCRLoader only supports English and needs to add some multilingual support.

``` js
this.log(`Starting OCR of ${documentTitle}`);
      const startTime = Date.now();
      const { createWorker, OEM } = require("tesseract.js");
      worker = await createWorker("eng", OEM.LSTM_ONLY, {
        cachePath: this.cacheDir,
      });
```
