Hash and Head in push refspec

[pnegahdar]

It seems like the following works fine:

err = repo.Repo.PushContext(ctx, &git.PushOptions{
	RemoteName: "my_remote",
	RefSpecs:   []gitConfig.RefSpec{
		"refs/heads/my_branch:/refs/heads/my_branch",
	},
})

But when the left reference is a <SHA> or HEAD it does not. e.g.:

err = repo.Repo.PushContext(ctx, &git.PushOptions{
	RemoteName: "my_remote",
	RefSpecs:   []gitConfig.RefSpec{
		"25309f687635b3e740c16bcb9c0c37bd0516ab03:/refs/heads/my_branch",
	},
})

Is this by design (git CLI supports it)? Can investigate if it isn't.

@pnegahdar We initially focused on refspecs for git pull, which work purely on references: https://git-scm.com/book/en/v2/Git-Internals-The-Refspec

But for push, yes, we should support SHA1 and HEAD: https://git-scm.com/docs/git-push#git-push-ltrefspecgt82308203
Support for this would be welcome.
