dotnet-ef does not work with dotnet enabled
Describe the bug
dotnet-ef tool cannot be used with dotnet (dotnet ef) when setting languages.dotnet.enable = true;.
It's pretty common to use dotnet-ef in .NET projects to run database migrations (Entity Framework); but for some reason when I try to use dotnet-ef, I get a message that it does not recognize the .NET runtime.
A typical way to install this tool is by running dotnet tool install --global dotnet-ef and export the binary path (export PATH="$PATH:$HOME/.dotnet/tools"). The installation seems to work fine but when I execute it (dotnet-ef --help, for example), I get the error shown.
AFAIK, dotnet-ef is looking for the DOTNET_ROOT env var, which for me is something like /nix/store/kfwdfmi8mw2x71sw9b3snfxr8pd61zv6-dotnet-sdk-wrapped-8.0.404.
Error Message:
You must install .NET to run this application.
App: /Users/robinsonmarquez/.dotnet/tools/dotnet-ef
Architecture: arm64
App host version: 8.0.11
.NET location: Not found

Download the .NET runtime:

Expectation
I would expect commands dotnet-ef --help or dotnet ef --help to work correctly by providing the help text.

Version devenv 1.3.1 (aarch64-darwin)
Just FYI: A workaround could be to nix profile install nixpkgs#dotnet-ef hoping that having it globally won't bring issues with local version of dotnet. So far has not happen to me.
