Turn off interactive - System namespace

[BillWagner]

Remove the interactive use in the System folder.

Contributes to dotnet/docs#50331

Notes for reviewers:

1. The diff looks a bit weird because the diff algorithm doesn't prefer words, so the i from "interactive" is outside of the diff, and the diff shows I removed the i from the following id= node.
2. I looked at several of the XML files, and I didn't find any remarks about using the interactive capability. Nor did I find other instances of include files with explanations.
