Improve "Libraries" definition on Module 2

[juanpflores]

I was taking the course and on Module 2 I found the definition of Libraries a bit broad:

Generic tools that implement well-known algorithms, provide statistical analysis or visualization, etc., which are incorporated in other software categories.

Proposed definition:

A software library is a collection of pre-written, reusable code that provides standardized implementations of common algorithms, utilities for tasks such as statistical analysis, data manipulation, and visualization, among others. These libraries are intended to be integrated into larger software systems, allowing developers to incorporate complex functionalities without the need to develop them from scratch.

I believe the new proposed definition would help readers understand the value of software libraries by adding more details about how developers use libraries to incorporate functionality without writing everything from scratch.

Thank you @juanpflores for taking the time to make suggestions for OS101! I will add this to our queue for dispositioning and we will update you if we have questions, implement your proposed definition, or if we decide to go with a modified definition.
