## Overview

- Ignores triggering the issue-label-automation workflow when a workflow
is triggered by dependabot[bot].
- why?: It always fails as the "check external contributor" action
doesn't find a legitimate user
- this seemed simplest way vs attempting to modify the imported action
to allow configuration to ignore dependabot or similar
- also introduces some minor/nit formatting with a whitespace change
