Delete global.json (#212)

 - There is a set of NuGet packages that are only applied in test projects by using the condition `"'$(IsTestProject)' == 'true'"`. To make this work the `csproj` for the test projects must have the `<IsTestProject>true</IsTestProject>` property defined. Adding this property manually shouldn't be needed because it should be added by the `Microsoft.NET.Test.Sdk` package however there seems to be an issue with this when running tests outside of Visual Studio. See [this GitHub issue](https://github.com/dotnet/sdk/issues/3790#issuecomment-1100773198) for more info.
 
-- When running `dotnet` CLI commands make sure you are at the `/MarkdownLinkCheckLogParser` folder so that the `global.json` is respected. If you don't you might get unexpected results when building the solution. As explained in [global.json overview](https://learn.microsoft.com/en-us/dotnet/core/tools/global-json):
-
-> The .NET SDK looks for a global.json file in the current working directory (which isn't necessarily the same as the project directory) or one of its parent directories.

 ## Deterministic Build configuration
 
 Following the guide from [Deterministic Builds](https://github.com/clairernovotny/DeterministicBuilds) the `ContinuousIntegrationBuild` setting on the [Directory.Build.props](/MarkdownLinkCheckLogParser/Directory.Build.props) is set to true, if the build is being executed in GitHub actions.
