diversity-advisor: Add @jflory7 biography (closes #78)
    
    This commit updates the Fedora Diversity Advisor docs page with my bio.
    I also updated a few outdated links and other info, like where to get in
    touch since we are not meeting regularly (at least, for now).
    
    Closes #78.
