Improve metrics output

Inizia dall’output di github/codeql-action/analyze mostrato nell’esecuzione del workflow collegata e traccia come vengono prodotti la tabella delle metriche e il messaggio di baseline; l’issue non indica alcun file sorgente né alcun test. Il lavoro è completato quando le righe delle metriche mantengono le colonne dei risultati distintive, la sezione delle metriche è separata visivamente e la frase di baseline appare una sola volta, chiarendo se il comportamento appartiene a CodeQL CLI o alle Java queries.

Version

CodeQL CLI: 2.8.5
CodeQL action: 1.1.8 (according to CODEQL_ACTION_VERSION environment variable)

Description

Currently (at least for Java projects) the metrics table printed at the end of github/codeql-action/analyze contains the same metric name multiple times, e.g.:

|                          Metric                          | Value |

(workflow run)

The issue might be that these queries have multiple result columns, but the table here only seems to contain the usages count, discarding the other columns. Maybe the underlying issue is therefore caused by CodeQL CLI or by the Java queries.

Additionally it might be good to add an empty line in front of "Analysis produced the following metric data:" (to separate it more clearly from the previous table). And also the "Counted a baseline of ..." sentence seems to be printed twice (workflow run).
