Re: [PATCH v4 5/8] refs: add `committer_info` to `ref_transaction_add_update()`

> The `ref_transaction_add_update()` creates the `ref_update` struct. To
> facilitate addition of reflogs in the next commit, the function needs to
> accommodate setting the `committer_info` field in the struct. So modify
> the function to also take `committer_info` as an argument and set it
> accordingly.
