commit trailers should be a list instead of a dictionary

[nickbroon]

Consider for example this linux kernel commit: https://gitlab.com/linux-kernel/stable/-/commit/1382999aa0548a171a272ca817f6c38e797c458c which has following trailers that include multiple cc and signed-off-by trailers:

And git interpret-trailers --parse ... will return all of these.

However the trailers() function returns a dictionary with only the last value for each token.

Of course, that would be much appreciated. Thanks for offering.
