Description

In #18847, a workaround was introduced that dealt with two problems

1. The use of new (non-public) dotnet versions in the repo
2. The difference in dotnet installations provided by the container image and expected by the sdk / ionide.

The second part is no longer necessary, therefore the ugly copy operations should be removed.
