VersionRange: Always output minor version for ~> and ^

[Geod24]

Dub was correct in outputting only the major version, however this can lead to some confusion for users
as pointed out in 2830. Accepting ~>5 but only exposing two states (~>5.0 and ~>5.0.0) will hopefully make things a bit more obvious.

@s-ludwig : I was about to close #2830 as WONTFIX but thinking about it more reducing possible state is probably best. Thoughts ?

I'd say the way you have it in the unit tests makes most sense. Following the general scheme, ~>1 would be the same as >=1.0.0, which doesn't really mean anything useful in SemVer semantics, so IMO, we shouldn't advertise it as a supported syntax, and neither output it. Disallowing it completely might be subject to a deprecation phase, though, considering that people might have picked up on it.

@s-ludwig : Anything else to do for now ? We probably want to deprecate it later but I don't think it's urgent.

[s-ludwig]

Should be good to go for now!
