Ilya Grigoriev 6fa8a25839 cli templates: include branches in short commit description
They are shown next to the change and commit id, since they are other names the
commit can be referred by. 

The description is separated from the branches by a ` | ` when there are
branches, so that one can tell the branches from the description without color.

The result looks like this: ![image](https://github.com/martinvonz/jj/assets/4123047/a38aff7b-2b47-49e6-8461-c42e8eb535a4)
