Remove score from trusty evaluator

[eleftherias]

Summary

This is a temporary fix, since this code will eventually be removed from Minder and rewritten as a ruletype.

The Trusty ruletype was getting very noisy because every package had a score of 0. This fixes the PR comment so it only comments when the package is malicious, deprecated, has activity beneath the threshold or provenance beneath the threshold.
It also renames Trusty to Stacklok Insight in the PR comment.

Fixes #4944
