DEV: Prettify negative numbers in reviewable score explanation (#23642)

This is an aesthetic change. Currently, if one of the scores involved in the reviewable score explanation is negative, we display it as: + -value. This changes that.

I also made an attempt at converting the component into GJS format. This is done as a separate commit.
