Add Sidebar for Model Selection to Improve User Navigation

[KashishJuneja101003]

🌟 Is your feature request related to a problem?: Currently, the app lacks a convenient navigation tool, requiring users to scroll through the page to select different machine learning models. This impacts the user experience, especially as more models are added.

💡 Describe the solution you'd like: Add a sidebar using st.sidebar.selectbox() for model selection. This would allow users to seamlessly switch between models without excessive scrolling.

🔀 Describe alternatives considered: Other navigational methods such as buttons or tabs, but the sidebar is most intuitive for this use case.

📄 Additional Context: A sidebar will enhance usability and overall UI consistency.

To be Mentioned while taking the issue: GSSoC extd and Hacktoberfest

Note:

• Please review the project documentation and ensure your code aligns with the project structure.
• Please ensure that either the predict.py file includes a properly implemented model_details() function or the notebook contains this function to print a detailed model report. The model will not be accepted without this function in place, as it is essential for generating the necessary model details.
• Prefer using a new branch to resolve the issue, as it helps keep the main branch stable and makes it easier to manage and review your changes.
• Strictly use the pull request template provided in the repository to create a pull request.
