Remove Epic Knights Steel Recipe

I have no idea why they haven't added a config option or something to the mod to make it so that you could do this without having to use a datapack or edit the mod jar file itself, but whatever. 🤷

I've tested this on 1.21.1 on Neoforge, and it seems to work just fine for me there.

Any other versions of Epic Knights / Magistu's Armory that also happen to have the exact same filepath to the steel ingot blasting recipe file in this pack should work just fine too, same as all other resource & data packs.
