+# Labels is an object where:
+# - keys are labels
+# - values are objects of { include: [ pattern ], exclude: [ pattern ] }
+#    - pattern must be a valid regex, and is applied globally to
+#      title + description of issues and/or prs (see enabled config above)
+#    - 'include' patterns will associate a label if any of these patterns match
+#    - 'exclude' patterns will ignore this label if any of these patterns match
