Update style cop

[Kalkwst]

Summary of Changes

This pull request updates StyleCop.Analyzers to version 1.2.0-beta.556 in the following projects:

• Algorithms
• DataStructures
• Utilities

The update to the beta version is necessary to support modern C# syntax, including nullable reference types and other new language features that are not recognized by earlier stable versions of StyleCop.

Key Changes:

1. StyleCop Update:

   • StyleCop.Analyzers has been updated from the previous version to 1.2.0-beta.556, which includes support for modern C# syntax.
   • This update resolves compatibility issues related to newer C# language features such as ?[] (nullable arrays), default interface implementations, pattern matching enhancements, and more.
   • The 1.2.0-beta version is now compatible with newer syntax and is essential for maintaining consistent coding style across projects using modern C#.

2. Warning Fixes:

   • Fixed all warnings introduced by the updated StyleCop rules. After the upgrade, several new style violations were flagged by StyleCop. These were addressed across the entire solution.
   • The following categories of fixes were applied:
     • Code formatting: Ensured consistent indentation, spacing, and alignment according to the new StyleCop rules.
     • Documentation comments: Added or corrected missing XML comments for methods, properties, and parameters to meet StyleCop’s documentation requirements.
     • Naming conventions: Corrected variable, method, and property names to adhere to the naming conventions enforced by StyleCop.
     • Code readability: Improved code readability by following best practices for method declarations, block statements, and spacing as suggested by StyleCop.

Why the Large PR?

I apologize for the large size of this pull request, but I opted for a fix-and-build approach. After updating StyleCop, I performed multiple fixes across all projects to ensure that the solution would build successfully and pass StyleCop analysis without any warnings.

Next Steps

• Please review the changes, focusing primarily on the warning fixes and any potential impacts the StyleCop upgrade may have on the projects.
• If any of the new StyleCop rules seem unnecessary or too restrictive, we can discuss further adjustments to the configuration.
