Update app.py

## Key Updates:
Dataset Selection for Fine-Tuning:

Added a dropdown (st.selectbox) to choose from the listed OSINT datasets.
Once a dataset is selected, it's loaded and displayed.
Integrated Fine-Tuning Process:

The model fine-tuning logic remains the same, but it now works with the selected dataset.
Smooth Integration:

The OSINT tools (GitHub analysis, URL fetcher) and dataset/model fine-tuning sections are smoothly integrated into the app, allowing users to work with both data and OSINT tools within a single interface.
