fixup: More generic signing_cb for future flexibility In the case that we want to build merge + commit, cherrypick + commit, or even just build a commit with signing callback, `git_rebase_commit_signature_cb` particular callback should be made more generic. We also renamed `signature_cb` to `signing_cb` to improve clarity on the purpose of the callback (build a difference between a git_signature and the act of signing). So we've ended up with `git_commit_signing_cb`.
