* feat: use built-in linter for csharp language
https://github.com/dotnet/format/issues/1268
* chore: remove dotnet-format installation from install-dotnet.sh
dotnet format is a part of .NET 6 SDK and shouldn't be installed separately anymore
* docs: update linter name for dotnet
instead of dotnet-format built-in format command from dotnet is used (points to the same repository as before)
* chore: update linter name for dotnet in tests
