Generated load scripts not working with dotnet fsi

Description

It seems that generated load scripts do not work well with dotnet fsi.

Repro steps

1. Check out this branch from Argu.
2. Run dotnet tool restore && dotnet paket restore.
3. Open dotnet fsi
4. Type #load ".paket/load/netcoreapp3.1/DocGeneration/docgeneration.group.fsx" ;;

Expected behavior

Should load dependencies in context.

Actual behavior

Complains about missing framework assemblies:

.paket\load\netcoreapp3.1\DocGeneration\docgeneration.group.fsx(42,1): error FS0078: Unable to find the file 'System.ComponentModel.Composition' in any of
 C:\Program Files\dotnet\shared\Microsoft.NETCore.App\3.1.1
 C:\Program Files\dotnet\sdk\3.1.101\FSharp\../../../packs/Microsoft.NETCore.App.Ref\3.1.0\ref\netcoreapp3.1
 C:\Users\eitsarpa\devel\public\Argu
 C:\Program Files\dotnet\sdk\3.1.101\FSharp\

Known workarounds

Manually delete framework assemblies loaded from script.

I’m just here to say thank you! the way for scripting is free again

The filtering of framework assembly references doesn’t seem to work correctly:

$ rg -i 'system\.componentmodel\.composition' packages/docgeneration/
packages/docgeneration/System.Runtime\System.Runtime.nuspec
79:      <frameworkAssembly assemblyName="System.ComponentModel.Composition" targetFramework=".NETFramework4.5" />
80:      <frameworkAssembly assemblyName="System.ComponentModel.Composition" targetFramework=".NETFramework4.6.2" />

$ paket why -g docgeneration system.runtime
Paket version 5.242.0
