I discovered, that you would need multiple links for one datapack, if you need to offer different versions of the datapack for each minecraft version.

E.g. if you have a datapack that contrains names of items an monsters that are renamed in one version (e.g. Zombie piglin) the datapacks would not ne compatible to older versions if you offer only one.

I recommend to add a way to rebuild the download section, that you have a upload field and a versions selection for each possible version.

By the way, the selection of the versions is shoould follow the changes of the datapack versions numbers here:

Because e.g. for 1.18 and 1.18.2 there are 2 different datapack versions that you should offer to be compatible.
