[Enhancement Request] - Improve debug messages for irrelevant workflow in some checks

[tromai]

Description

Currently there are 3 places where debug messages like

[DEBUG] Workflow <workflow_name> is not relevant. Skipping...

are printed out.

1. macaron/src/macaron/slsa_analyzer/checks/build_as_code_check.py

   Line 163 in 23c7fdb

   logger.debug("Workflow %s is not relevant. Skipping...", callee.name)

2. macaron/src/macaron/slsa_analyzer/checks/github_actions_vulnerability_check.py

   Line 110 in 32aa0cc

   logger.debug("Workflow %s is not relevant. Skipping...", callee.name)

3. macaron/src/macaron/slsa_analyzer/checks/trusted_builder_l3_check.py

   Line 126 in 4235041

   logger.debug("Workflow %s is not relevant. Skipping...", callee.name)

Even though the context and reason why the message is printed out are different.

Proposed Feature

We can improve the debug message by adding a small description why a workflow is treated as irrelevant.
