council: Amend history of the FCA role title
    
    This commit fixes the story and original title of the Fedora Community
    Architect and its many different historical iterations. This came up in
    private message with @mattdm, when he pointed out to me that I missed
    some details in how I explained the history of the role title and how we
    got to where we are today.
    
    Furthermore, based on the suggestion of @mattdm and other low-vision
    users on Fedora Discussion, I dropped the use of punctuated acronyms as
    this did not have the desired impact I thought I was making for screen
    reader users. So, to respect the feedback of those who participated in
    the discussion, I am ending this precedent and will move back to
    acronyms not broken with punctuation.
