git-artifacts: allow specifying repo/ref via workflow_dispatch

With this change, users can specify the branch and repository from which they want to build Git for Windows' artifacts, via the `ref` and `repository` inputs. This allows e.g. building `refs/heads/seen` of `git/git` (even if no `git-artifacts` workflow is configured in that repository), or `refs/pull/<number>/merge` for a given Pull Request.
