Don't include the SDK in our helix payload (#6918)

* Don't include the SDK in our helix payload

I noticed that the tests included the latest SDK - including the host -
in our helix payloads.

This is a large amount of unnecessary downloads and it also makes it so
we use the latest host on the older frameworks which can fail when the
latest host drops support for distros.

Since our tests shouldn't need the full CLI, remove this from our helix
payloads.

We'll instead get just the runtime we need through `AdditionalDotNetPackage`

* Place Helix downloaded runtime on the PATH

Helix only sets the path when the CLI is included, however we don't
need the CLI.
