• some casing

Pull Request Overview

Improvements to the reporting documentation in docs/report.md focusing on formatting consistency and casing corrections

• Standardized product and project names (e.g., NuGet, TeamCity)
• Converted inline version notes into markdown [!NOTE] blocks
• Reformatted CLI examples with code fences and backticks for consistency

• Add a preceding descriptive line (e.g., 'For dotnet test or dotnet vstest:') above this code block to clarify which command this example applies to.

```shell

docs/report.md:184

• This example isn't wrapped in a code block; consider enclosing it in a shell fence for consistency with the other CLI snippets.

vstest.console.exe Tests.dll /logger:"trx;LogFileName=relativeDir\logFile.txt"
