fix: dependabot config to ignore black

[WilliamBergamin]

Updates Dependabot config to ignore the black dependency. We're ignoring it because we are intentionally using the specific version compatible with the project's minimum supported Python version.

Testing

The ci pipeline should pass

@WilliamBergamin LGTM and I am curious if ruff might be an interesting replacement upcoming? At this time we seem to have matching python version support! 🐍
