Email aliases: Swap diversity@fp.o from @jflory7 to @siddharthvipul1
    
    This commit swaps the recipients of the diversity@fp.o email address
    from @jflory7, the outgoing D&I Advisor, with @siddharthvipul1, the
    incoming D&I Advisor for Fedora 34.
    
    I believe that `roles/fasjson` is current and `roles/fas_client` is
    retired from FAS2, but I could not find confirmation that it is retired
    or deprecated. So, I updated both roles.
    
    CC: @riecatnor @mattdm, who are also included as recipients to this
    email address alias.
    
    CC: @lilyx @ramyaparimi @t0xic0der @mouse, sharing as a "For Your
    Information". Did you know we have a diversity@fp.o mail alias? Now you
    do. :wink:
