Title: [https://github.com/apache/maven/issues/10389] tests(maven#10389): Adding DefaultDependencyResolverResultTest

Added unit tests for DefaultDependencyResolverResult Following this checklist to help us incorporate your contribution quickly and easily:

• [x] Your pull request should address just one issue, without pulling in other changes.
• [x] Write a pull request description that is detailed enough to understand what the pull request does, how, and why.
• [x] Each commit in the pull request should have a meaningful subject line and body. Note that commits might be squashed by a maintainer on merge.

Using DefaultType will remove 150 lines of code and will make the test more readable.

Done.

Use a method or constants instead of those long calls to the constructors.

Came up with a reusable method.
