cli: color author and commiter names yellow

When `format_short_signature(signature)` is set to `signature.name()` the author names are not yellow like other signature types (eg email and username). When the commit signatures have no colors, they blend in making it hard to distinguish between signatures and commit messages.

If just `name` were set to `yellow`, just like email and username, it affects the colorization of branch names making them also yellow despite them being designated as magenta. Setting `author` and `committer` to `yellow` is specific enough to allow branches to keep their colors while still coloring signature names. This is known to affect signatures in both 'log' and 'show'.
