feat: Add VariableArgumentsForStrings to demonstrate varargs with formatted string lists

WHAT the code does:
Defines a VariableArgumentsForStrings class with:
- showList(int start, String... S): prints each string argument as a numbered list, starting at the given index.
In main():
- Calls showList(5, "John","Smith","Ajay","Ahmed","Mark","List of name show you variable arguments").
- Prints the provided names and messages numbered sequentially from 5.

WHY this matters:
Demonstrates varargs with non-primitive types (String).
Shows how to combine fixed parameters (start) with varargs (String... S).
Illustrates formatting of list-like output, a common console programming task.
Highlights flexibility in method design: caller can pass any number of string arguments.

HOW it works:
main() passes multiple string arguments along with a starting index.
showList iterates over the array S:
- Prints each string prefixed with an incrementing number starting at `start`.
Example output begins with `5. John`, followed by incremented labels.

Tips and gotchas:
Varargs must be the last parameter in the method signature; here, start comes first.
The numbering logic is flexible—uncommenting `i+1` could start numbering from 1 regardless of the start parameter.
Be cautious of formatting: concatenating integers and strings directly may lead to subtle bugs; string formatting methods like String.format() improve readability.
If no varargs arguments are passed, the loop simply does not execute.

Use-cases:
Educational demo of combining fixed parameters with varargs in Java.
Useful for creating flexible list-printers, menus, or logging utilities.
Foundation for building formatted output utilities that adapt to variable input sizes.

Short key: class-variableargumentsforstrings varargs string-list-formatting.
