Mention --skip-install in the @fedify/cli changelog section too

Per review on #776, the --skip-install option is surfaced to users
through `fedify init` in the CLI, while `@fedify/init` can also be used
standalone.  It therefore belongs in both the @fedify/cli and @fedify/init
changelog sections: the full explanation stays under @fedify/init and the
@fedify/cli entry cross-references it.
