Support for .net 5

Describe the bug stryker does not support .net5 framework. The issue is with the library used by Stryker (Buildalyzer). The BuildAnalyzer is parsing the targetframework of the project and while parsing the target framework it does not the get format it needs which is netcoreappx.x

Logs dotnet stryker --solution-path <solution_path> --reporters “[‘json’]”
