Trainee Maintainers (traintainers) no longer appear within the Engineering Projects page
requested to merge 3518-trainee-maintainers-traintainers-no-longer-appear-within-the-engineering-projects-page into master
In an attempt to format 'Trainee_maintainers' to 'Trainee maintainers (#3448 (closed)), this inadvertently broke Trainee maintainers from appearing on https://about.gitlab.com/handbook/engineering/projects.
I also noticed that my username had not been updated, so I fixed that also
Closes #3518 (closed)
