[BUG] Wrong DOTNET_ROOT inferring on OSTree-style .NET installations

[GGG-KILLER]

Describe the Issue

The DOTNET_ROOT env var is set incorrectly on Linux when .NET is installed in OSTree style (i.e. dotnet binary is inside a bin directory and not in the root of the .NET installation).

I have implemented a fix in the build script for my installation however this would be best solved upstream.

Steps To Reproduce

1. Install a Linux distro where .NET is installed in OSTree style (e.g. NixOS)
2. Install the extension (and patch the binaries if you're on NixOS)
3. Configure the extension to use the installed .NET
4. Open a .NET project
5. Have the extension fail with ".NET is not installed"

Expected Behavior

Extension detects that the dotnet binary is in the bin dir and goes up another directory to get DOTNET_ROOT.

Environment Information

• OS: NixOS 23.11.20230825.5690c42
• VSCode Version: 1.81.1
• Extension Version: 0.4.6

Seems like this has been solved by replacing readlink with realpath as was done in dotnet/vscode-csharp#6230 as I've found out in dotnet/vscode-csharp#6239.
