feat: add a YouTube video link to Rust memory management (#7438)

* Added a YouTube video link to Rust memory management

In this video, he provides a clear explanation of Rust's ownership system, including example code. It could be helpful for understanding ownership concepts.

* Update src/data/roadmaps/rust/content/100-introduction/102-memory-safety.md

 <!-- Adding content on Zero-cost Abstraction -->
 
 Zero-cost abstraction is another key concept Rust implements. In general, abstractions in programming languages allow code to be written at a high level (like in Python), while being able to run at a low level (like in C). However, these abstractions often come with a runtime cost. In contrast, Rust aims to provide many useful abstractions, such as iterators and closures, that don't sacrifice runtime performance. This means you can write high-level code in Rust, and the Rust compiler will optimize it to run as fast as manually written low-level code.
