Fixes #10450

BREAKING CHANGE: the `zsh-navigation-tools` plugin now bundles the version from the
zdharma-continuum project, which republished the projects that psprint deleted (we
don't yet know yet why). In theory this change doesn't break anything, but be aware
of the change and that the upstream repository now lives somewhere else.

This is an improvement (in my opinion) to the `brews` command that prints each leaf formula (in white), followed by its dependencies (in blue), on each line. Compared to the existing flat list of formulae, the new layout is both more compact and more informative, by differentiating leaves from dependencies at a glance.
