Specify Minecraft version for fabric mod

### The Problem

Currently, WorldEditFabric does not specify a Minecraft version in its `fabric.mod.json`, which leads to confusion, wasted time, and avoidable crashes.

Consider the latest 1.19 versions - WorldEdit for 1.19.3 (version 7.2.13) is not compatible with 1.19.2, which should be obvious, but this isn't specified in the mod definition, JAR name, or anywhere else, other than the CurseForge mod release title. It's worth noting that even the CurseForge download isn't obviously for strictly 1.19.3, since it's categorized under the 1.19 version - see below.


When a release is listed as for 1.19 on the mod's homepage, users will expect this to work for all 1.19 versions.

### A Solution

Add the appropriate version to `fabric.mod.json` and update it when appropriate.

### Alternatives

Correct the version grouping on CurseForge to make it more apparent that 7.2.13 is not for `1.19.*`.

### Anything Else?

I cannot see why this would cause any issues.
