lib min_heap: add brief introduction to Min Heap API

Browse Source 
A short description of the Min Heap API is added to the min_heap.h,
explaining its purpose for managing min-heaps and emphasizing the use of
macro wrappers instead of direct function calls.  For more details, users
are directed to the documentation at Documentation/core-api/min_heap.rst.

/*
* The Min Heap API provides utilities for managing min-heaps, a binary tree
* structure where each node's value is less than or equal to its children's
* values, ensuring the smallest element is at the root.
*
* Users should avoid directly calling functions prefixed with __min_heap_*().
* Instead, use the provided macro wrappers.
*
* For further details and examples, refer to Documentation/core-api/min_heap.rst.
