Explicit Returns on Validation Plugin

## Explicit Returns on Validation Plugin

Please describe the desired new functionality:

### Current Behavior

On the branch currently in #169, when a check fails, the message looks like this:

> ❌ Settings : Error: `Branch protection required_approving_review_count cannot be overidden to a lower value`

Expanding the line does not show anything.

### Expected Behavior

Expanding the message displays, at a minimum, the file that was changed, or even better, a list of which repositories would be affected.

Essentially, an explicit message for the user, so that they have better info with which to approach their support team.
