AWS AMI entry for ap-southeast-2 (Sydney) missing from Stretch AMI page

[paul]

Hi folks, not sure who the current AMI maintainer is, but:
https://wiki.debian.org/Cloud/AmazonEC2Image/Stretch

ap-southeast-2 (Sydney) is missing from the listing - searching AMIs by 
account number show that the region was getting this AMI from the 
previous build 2019-05014 and earlier.

Also missing from this list are the three Chinese regions, but I don't 
know if there are other issues there. Those are new regions, though, 
whereas ap-southeast-2 is fairly old :)

Cheers,

Paul
