Remove --decorate from katas

[JKrag]

The --decorate option is default in git log, and provides no value in
the form where it is currently used in the examples.

Can't seem to find the documentation that says that decorate is default. Otherwise 👍

@RandomSort That was the hardcore answer to @sofusalbertsen's question :-)

I would probably have posted:

$ git help log
....
       --no-decorate, --decorate[=short|full|auto|no]
           Print out the ref names of any commits that are shown. If short is
           specified, the ref name prefixes refs/heads/, refs/tags/ and
           refs/remotes/ will not be printed. If full is specified, the full
           ref name (including prefix) will be printed. If auto is specified,
           then if the output is going to a terminal, the ref names are shown
           as if short were given, otherwise no ref names are shown. *The
           default option is short.*

Doing that, however, it is worth noticing that the default is actually now short, even though the commit you linked to suggest auto in the headline (although the code/tests seems to collaborate short)
