IDE0150: Prefer 'null' check over type check

[siagupta0202]

Link to the issue description: https://learn.microsoft.com/en-us/dotnet/fundamentals/code-analysis/style-rules/ide0150

Overview

This style rule flags use of the is {type} statement when is not null can be used instead. Similarly, it flags use of the is not {type} statement in favor of is null. Using is null or is not null improves code readability.
