fix GolangVersion version comparison

[keshav-space]

GolangVersion("v1.1.0") is not raising InvalidVersion error leading to all sorts of problem

>>> from univers.versions import GolangVersion
>>> GolangVersion("v1.1.0") == GolangVersion("1.1.0")
False

@keshav-space IMO the leading v is not a problem, actually the version comparison is the problem please checkout this branch https://github.com/TG1999/univers/tree/fix_comparison

>>> from univers.versions import *
>>> GolangVersion("v1.0") == GolangVersion("1.0")
True
