Remove support for GitVersion.Commandline && GitVersion.Portable

[arturcic]

Remove support for GitVersion.Commandline && GitVersion.Portable in favor of the tar.gz/zip files we generate at each release, and available on the release page.

I suggest we remove the support for these 2 or at least GitVersion.Commandline as anyway both embed the exact same executable as the one from tar.gz/zip archives.

Anyone that uses these 2 can switch to use the archives instead.

The reason is to simplify the build infrastructure and reduce the duplicates.

@asbjornu @gep13 Ideas?

I've never understood the difference between GitVersion.CommandLine and GitVersion.Portable so I've always used the former. Can we deprecate GitVersion.Portable and refer people to GitVersion.CommandLine instead?

[arturcic]

Well honestly I would refer people to use the zip archive in this case, as both GitVersion.CommandLine and GitVersion.Portable use the archive version, just a different delivery channel - via nuget.org and chocolatey.

[asbjornu]

The problem I see with the ZIP archive is that it's not immediately executable.

[gep13]

This would be my concern as well. The Chocolatey package sets up the shim to allow for immediate execution once installed.

Ok then, we keep them.
