fix: opt for simpler tileset updates changelog (CleverRaven#63571)

my dinamic tileset changelog is a little broken, I can't quite get it to
work like I want to; just ehh have a static list of the tilesets hosted
at the two main repos under liks to the upstream release, they have nice
looking changelogs, good!

this sorta works as is, only you need someone with write permissions to
do a little editing; don't like - this instead
