refactor: Version.__repr__() should return a Version() like string

[dl6nm]

Implement a better representation of the both dunder methods __repr__ and __str__.

As summarized on Stack Overflow...

Implement __repr__ for any class you implement. This should be second nature. Implement __str__ if you think it would be useful to have a string version which errs on the side of readability.

So __repr__ should output something like this:

Version(major=1, minor=2, patch=3, prerelease=None, build='15-gbfc10a8-dirty')

And __str__ should output something like this:

1.2.3+15-gbfc10a8-dirty
