Change how the helix tests work with the framework package in CI

[marcpopMSFT]

In this PR, #42822, I disabled the framework toolset package for all of our tests. However, Daniel pointed out that we don't actually expect customers to be in this state so we're not longer testing the default state for many customers.

I disabled this because the test projects were trying to find version 9.0.100-ci of the package and not finding it as it was just built.

This issue is to track whether we can copy the package into our test nuget cache (is it on the helix test machine already and just not in the cache or does it need to be copied into our folder to get copied over?) and then reenable using the package in the tests.

This test seems to be failing again, thanks for helping in the past. I'm going to use this issue to track the problem again.
