Add beginner LLM Fine-Tuning tutorial under Python miscellaneous

[i-wav]

Description

This pull request adds a beginner-friendly tutorial introducing Large Language Models (LLMs) under the Python → Miscellaneous section. The tutorial covers foundational concepts such as what LLMs are and how they are used, making it suitable for newcomers.

Motivation and Context

Large Language Models are now a core part of modern software and machine learning workflows, but there was no introductory LLM-related tutorial in the repository. This change helps bridge that gap by providing an accessible starting point without restructuring existing sections.

How Has This Been Tested?

• Verified that the tutorial link points directly to the intended resource.
• Confirmed that the entry follows the required [Title](link) format.
• Ensured placement under the correct Python subsection.
• Checked spelling, grammar, and formatting consistency.

Types of changes

• Content Update (change which fixes an issue or updates an already existing submission)
• New Article (change which adds a new tutorial)
• Documentation change
