fix(deps): remove deprecated husky commands

Husky 9.1 now warns when doing some rebase of patches:
husky - DEPRECATED

Please remove the following two lines from .husky/prepare-commit-msg:

#!/usr/bin/env sh
. "$(dirname -- "$0")/_/husky.sh"

They WILL FAIL in v10.0.0

Remove the deprecated lines.
