bundle: remove ignored & undocumented "--verbose" flag

In 73c3253 (bundle: framework for options before bundle file,
2019-11-10) the "git bundle" command was refactored to use
parse_options(). In that refactoring it started understanding the
"--verbose" flag before the subcommand, e.g.:

    git bundle --verbose verify --quiet

However, nothing ever did anything with this "verbose" variable, and
the change wasn't documented. It appears to have been something that
escaped the lab, and wasn't flagged by reviewers at the time. Let's
just remove it.
