fix: include count in error message

[dkarter]

Motivation

Injects the count into the validation error message, e.g., should be at least 8 character(s)

This PR is based on the formatting PR, but because I opened it via the fork, GitHub won't let me set the formatting PR as the base, which is why the diff is so large. I recommend just looking at the last commit for review.
