CLI Tools aren't being restored properly now #2854

Description

CLI Tools aren't being restored properly now. I'm getting errors like Version for package dotnet-mono could not be resolved when trying to run a tool https://github.com/fsprojects/Paket/releases/tag/5.117.0 seems to be the culprit.

Repro steps

Please provide the steps required to reproduce the problem

paket.depedencies includes a dotnet tool like clitool dotnet-mono 0.2.1 and include that in your paket.references

Do a dotnet restore dotnet build dance then try to use that tool.

I'll try to get a github repo repro.

Expected behavior

dotnet tools are there

Actual behavior

dotnet tools appear to not be there

Known workarounds

Revert to earlier version
