Improve language tag

Hi! As the model is multilingual, this is a PR to add other languages than English to the language tag to improve the referencing. Note that 29 languages are announced in the README, but only 13 are explicitly listed. I was therefore only able to add these 13 languages.

-## Introduction
-
-We are thrilled to release our latest Eagle2 series Vision-Language Model. Open-source Vision-Language Models (VLMs) have made significant strides in narrowing the gap with proprietary models. However, critical details about data strategies and implementation are often missing, limiting reproducibility and innovation. In this project, we focus on VLM post-training from a data-centric perspective, sharing insights into building effective data strategies from scratch. By combining these strategies with robust training recipes and model design, we introduce Eagle2, a family of performant VLMs. Our work aims to empower the open-source community to develop competitive VLMs with transparent processes.
-
-
-
-In this repo, we are open-sourcing Eagle2-2B, a lightweight model that achieves remarkable efficiency and speed while maintaining solid performance.

-## Quick Start
-
-
-
-We provide a [demo inference script](./demo.py) to help you quickly start using the model. We support different input types: 
-- pure text input
-- single image input
-- multiple image input
-- video input
-
-### 0. Install the dependencies
-
-```bash
-pip install transformers==4.37.2
-pip install flash-attn
-```
-**Note**: Latest version of transformers is not compatible with the model.
-
-### 1. Prepare the Model worker

+## Introduction
+
+We are thrilled to release our latest Eagle2 series Vision-Language Model. Open-source Vision-Language Models (VLMs) have made significant strides in narrowing the gap with proprietary models. However, critical details about data strategies and implementation are often missing, limiting reproducibility and innovation. In this project, we focus on VLM post-training from a data-centric perspective, sharing insights into building effective data strategies from scratch. By combining these strategies with robust training recipes and model design, we introduce Eagle2, a family of performant VLMs. Our work aims to empower the open-source community to develop competitive VLMs with transparent processes.
+
+
+
+In this repo, we are open-sourcing Eagle2-2B, a lightweight model that achieves remarkable efficiency and speed while maintaining solid performance.
+
+
+
+
+
+
+
+

+## Quick Start
+
+
+
+We provide a [demo inference script](./demo.py) to help you quickly start using the model. We support different input types: 
+- pure text input
+- single image input
+- multiple image input
+- video input
+
+### 0. Install the dependencies
+
+```bash
+pip install transformers==4.37.2
+pip install flash-attn
+```
+**Note**: Latest version of transformers is not compatible with the model.
+
+### 1. Prepare the Model worker

+```
+
+- Multiple image input
+```python
+prompt = [
