As part of the recent batch of changes and bump to the unreleased v0.12.0, the CLI args were updated a bit as part of the switch to Clap.

Current versions of the hook scripts run rusty-hook run --hook "${hookName}" "${gitParams}" providing the git params as a positional argument that's empty in cases of hooks that have no args. This is problematic with clap which doesn't allow explicitly empty values by default.

The impact of this would be users currently using rusty-hook in multiple projects would experience rusty-hook failures after updating one project (and thus updating the rusty-hook cli to v0.12.0) in all other projects.

To address, we need to update the clap interface to accept that arg for legacy/BC purposes
