Using loom.modVersion fails because it tries to find a fmj

[triphora]

This appears to be a regression from Loom 1.0 -> 1.1.

Code in Loom 1.0 / Code now

As you can see, the new code expects a fabric.mod.json.

I use this to determine my mod's version. I prefer setting it in quilt.mod.json and not having to deal with processResources and all that stuff. version = "$loom.modVersion+${libs.versions.minecraft.get()}"
