fix(scorecard-enforcer): fix score parsing; make score check advisory

The minimum-score check was parsing from the wrong SARIF path
('.runs[0].tool.driver.properties.score') which always returned 0.
Correct path is '.runs[0].properties.metricResults[] | AggregateScore'.
Score check is now advisory (informational only) — hard enforcement
is via scorecard.yml + the OSSF webapp badge.
