fix(semver): Minecraft 1.20 crashing the semver parser

Browse source 
Minecraft doesn't use semver, and as such, sometimes it can cause problems, like in this case: `1.20` is not a valid semver version, but we must deal with it anyway, we've made the `<patch>` component optional, defaulting it to `0` if missing
