fix: respect verbosity per GitHub Actions env var (#346)

This was an oversight when switching to git-bot-feedback in #304.

It restores the behavior in which verbosity is auto-enabled if the
`ACTIONS_STEP_DEBUG` env var is asserted.

* Enhanced debug logging configuration to respect REST client settings
in addition to command-line verbosity options.
