What does this do?

Updates gitlab username for team member Bilal Husain on GitLab team page: https://about.gitlab.com/company/team/#bilal

Why?

It currently links to https://gitlab.com/bilal, which is not an active/registered username.

We sometimes use the GitLab username as it appears in team.yml to determine access to things that non-team members don't have, so we should update it
