Closes #10518

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.
