I do have dotnet installed, evident as when I run,
```
❯ dotnet --list-sdks
6.0.302 [/home/zekiah/dotnet/sdk]
7.0.100-preview.6.22352.1 [/home/zekiah/dotnet/sdk]
❯ dotnet --list-runtimes
Microsoft.AspNetCore.App 6.0.7 [/home/zekiah/dotnet/shared/Microsoft.AspNetCore.App]
Microsoft.AspNetCore.App 7.0.0-preview.6.22330.3 [/home/zekiah/dotnet/shared/Microsoft.AspNetCore.App]
Microsoft.NETCore.App 6.0.7 [/home/zekiah/dotnet/shared/Microsoft.NETCore.App]
Microsoft.NETCore.App 7.0.0-preview.6.22324.4 [/home/zekiah/dotnet/shared/Microsoft.NETCore.App]
```
 , you can see everything is installed as expected, when I run `which dotnet`, I get `/home/zekiah/dotnet/dotnet`, I suspect this may be an issue as godot is only seeming to look in `ERROR: The host fxr folder does not exist: /usr/share/dotnet/host/fxr` for dotnet. When searching within `/home/zekiah/dotnet/dotnet`, the `host/fxr` dir does exist there.

### Steps to reproduce

- Install dotnet via the install scripts, or some other method that does not result in the dotnet directory not being located in /usr/share/dotnet/
