style: use monospace for changeset messages Similar to commits 9005c37dbe21 and 6e65c2153baa that make PR descriptions display in a monospace font, apply monospace on changeset messages. Note that in the files template, the reference to the non-existing 'commit' class can be replaced instead of appending to it.
