Works on 1.21.5

Just to tell you that Data Loader seems to work in 1.21.5! Tried on singleplayer to create a new world with the experiments tweaked on in config, showed as enabled on the datapack screen.

Just didn't tested if this works on dedicated server yet.

Regardless, i think you can mark it as compatible with 1.21.5 on Modrinth

@Commander07 a small addendum: despite the similarity code-wise between 1.21.5 and the 2025 April Fools snapshot 25w14craftmine, Data Loader will crash when i try to load it on that version, even using a compatibility-enabler mod as I Can't Believe It's Not 1.21.5, here's the latest.log of my last attempt to run.

Not really a priority for a fix (i would prefer a build for one of the 1.21.6 snapshots to quench our thirst about this amazing upcoming version, tbh), but would be interesting to have it available to craftmine too.

I Can't Believe It's Not 1.21.5 can't change the class(es) mixins target so it would need a separate version of Data Loader.

I think all that would need to change to work with 25w14craftmine is MinecraftServerMixin changing to target class_10958 with loadDataPacks changing to method_68919 and createDataPackSettings changing to method_68920.

Unfortunately seems like Commander is away for a while (i'm afraid when 1.21.6 gets release it will not support the latest build of data loader).

If it's not too much trouble, @Chocohead could you do a PR with these changes you mentioned? At least i could build myself the fork and try here.

Done: #26
