for v3, "dotnet add package" does not respect the cache folders while offline, and halts the process after trying to connect a repo.

funny thing is out of 3, that repo does not even have the package I try to add while others have the cached version already.

open a command prompt and use the following commands to reproduce

mkdir online
cd online
dotnet new console
dotnet add package Microsoft.EntityFrameworkCore

after this the package and dependencies should be available in caches for offline use. but there is a problem with the source "dotnet-windowsdesktop" thus it is not cached.

now disconnect the internet and continue

cd ..
mkdir offline
cd offline
dotnet new console
dotnet add package Microsoft.EntityFrameworkCore

and get this error. though others repos have the cached package files and package added from cache while online as can be seen in the previous step, just because one of repos cant be reached and other caches are discarded to continue adding the package, even though the package is not available from this repo
