Description

Suggested by @tomjaguarpaw in the HF slack. Joachim suggested that we might want to suppress this when active-repositories is the default. I think it wouldn't be too much line noise either way, especially since this error is not going to come up constantly, and when it does, the more context the better.

Research direction
Investigate the error handling for unknown packages in cabal install, likely in the module that processes package queries. The goal is to include a list of active repositories in the error message. Check the condition for suppressing this when active repositories is the default, as mentioned in the issue. Look for existing functions that retrieve active repositories and see how they can be integrated into the error output.
