help: Make version and help flags consistent
These flags are presented as POSIX/GNU-style long-form flags (double-dash), whereas the rest of our CLI flags as seen in sub-commands are presented as single-dash options. While both work in both cases (on part of the flag package allowing double dashes as well), we converge around the single-dash form, so the basic help text here should be consistent.
