Updatelist.xml

PS5 Checks for updates by sending a GET request to fus01.ps5.update.playstation.net/update/ps5/official/tJMRE80IbXnE9YuG0jzTXgKEjIMoabr6/list/us/updatelist.xml where 'us' is your consoles region, parsing it to find download links to *.PUP files

the format of updatelist.xml is the same as ps4-updatelist.xml from PS4 and psp2-updatelist.xml from psvita. the only difference now is that its not called "ps5-updatelist.xml" but rather just 'updatelist.xml' and sony added a random string into the url and the "offical/" folder.

Example updatelist.xml
