docs: enhance `texify` model documentation and usage examples

- Add a base model reference to `vikp/texify`
- Include a pipeline tag for `image-to-text`
- Provide detailed usage instructions for the `texify-fp16-onnx` model
- Add an example Python code snippet for using the model with `optimum[onnxruntime]`
- Include input and output image examples for visualization

+
+https://huggingface.co/vikp/texify with fp16 ONNX weights, shoutout to https://huggingface.co/Xenova/texify
+
+## Usage (`optimum[onnxruntime]`)
+
+If you haven't already, you can install the optimum with the onnxrumtime backend
+
+```bash
+pip install "optimum[onnxruntime-gpu]"
+```
+
+**Example:**
+
+```python
+from optimum.onnxruntime import ORTModelForVision2Seq
+from optimum.pipelines import pipeline
+
+model = ORTModelForVision2Seq.from_pretrained("Spedon/texify-fp16-onnx", provider="CUDAExecutionProvider")
+texify = pipeline(
+    "image-to-text",
+    model,
+    feature_extractor="Spedon/texify-fp16-onnx",
+    image_processor="Spedon/texify-fp16-onnx",
+)
+image = (
+    "https://huggingface.co/datasets/Xenova/transformers.js-docs/resolve/main/latex.png"
+)
+latex = texify(image, max_new_tokens=384)
+print(latex)
