Add Abbreviation Dynamic Programming Algorithm

[AliAlimohammadi]

Description

Adds the Abbreviation problem solution to the dynamic programming module.

Problem Statement

Determines if string a can be transformed into string b by capitalizing
zero or more lowercase letters and deleting all remaining lowercase letters.

Implementation Details

• Uses dynamic programming approach
• Time Complexity: O(n * m)
• Space Complexity: O(n * m)
• Includes comprehensive test cases from HackerRank

Checklist

• Code follows the repository's style guidelines
• Tests pass locally (cargo test)
• Code formatted with cargo fmt
• No warnings from cargo clippy
• Updated mod.rs to include new module

Hi @siriak, Could you please check this PR? Thanks.

Hi, there are already enough examples of dynamic programming in this repository and we don't add problems from LeetCode and similar sites (only a few if needed to demonstrate a programming technique)
