Tooling: fix issue labels validation

[iangmaia]

This PR fixes the regex applied when we run labels validations on issues.
The ending part of the regex *$ isn't really necessary and was breaking the regex match.

I'm not too familiar with the Dangermattic workflow this ties in with, but this change looks good for matching labels starting with type: and feature: .

If we wanted to use regex that matches the entire label we could check for ^type: .+ and ^feature: .+, but that's only needed for exact matches.

Good suggestion, though! I'll add it just to be a bit more precise.
