[Ambassadors] Instructions on how to get an Ambassadors Polo Shirt

[Christoph Wickert]

My fellow ambassadors,

in order to prepare a new round of ambassadors polo shirts for EMEA, I
have outlined the process how to get one in the wiki at
https://fedoraproject.org/wiki/Polo_Shirt#Ordering_polo_shirts

Unfortunately the instructions currently only cover the EMEA region. If
somebody knows what the process is like in APAC, NA or LATAM, please add
the instructions to the wiki or let me know who is in charge of the
polos in your region.

Thanks in advance,
Christoph
