Reduce logging of List final flexmark options to debug level

This resolves #60 ensuring normal execution of processMarkdown does not produce any INFO output.

Produces a single debug level message for for final flexmark option information

Aside: I tried looking up if maven was in batch mode, so we could selectively provide less feedback when not in an interactive environment, but did not find a useful example.

Thanks for the PR. In normal execution it's reasonable to produce less output and these log messages were indeed more of a debug type.

Thanks for merging, sorry I could not figure out how to detect if it is in batch mode (which would of provided the best of both worlds).

@jodygarnett you can use the injected MavenSession session field to know if Maven is executed in interactive or batch mode:

this.session.getSettings().isInteractiveMode()

MdPageGeneratorMojo.java already have a session field available:

markdown-page-generator-plugin/src/main/java/com/ruleoftech/markdown/page/generator/plugin/MdPageGeneratorMojo.java
