Update Syria Flag Emoji

@spencer-nelson @jasoncuster

Syria has officially adopted a new flag with green, white, and black stripes and three red stars in the center, as depicted below. iOS, OneUI, WhatsApp, Jdecked Twemoji, and OpenMoji emoji fonts have already redesigned their Syria flag emojis to reflect the new one. It would be great if FluentUI could update the Syria flag to reflect this redesign.
