Fixed all warning in snippets project

[Copilot]

Pull Request Overview

This PR fixes build warnings in the NUnit documentation snippet projects by adding warning suppressions and cleaning up unnecessary using statements. The main changes include adding NoWarn configurations to suppress NUnit analyzer warnings, adding targeted pragma directives for nullability warnings, reformatting XML indentation, and removing redundant using statements that are covered by implicit usings.

• Added NoWarn configuration to suppress NUnit analyzer warnings (NUnit2007, NUnit2009, CS7022) at the project level
• Added targeted pragma directives to suppress specific warnings in test code examples
• Removed redundant explicit using statements now covered by implicit usings
• Reformatted XML indentation in project files for consistency

@SeanKilleen I haven't touched the files the markdown linter complains about now.

[SeanKilleen]

@OsirisTerje I'll fix this shortly. I think the issue is that I'm probably using latest rather than pinning to a version, and they likely added a new rule that we don't care about. Will investigate and fix ASAP.

When the linter was successful it was running version markdownlint-cli2 v0.18.1 (markdownlint v0.38.0) and now markdownlint-cli2 v0.19.0 (markdownlint v0.39.0)

@mikkelbu yes, as I noted, it likely added a new rule that we need to disable.

I will fix this up.
