Previously, the implicit sort ordering of modules ensured that the "plugins" startup module ran before the "startup" startup module. That no longer holds when experimenting with alternate stores that might use a subtly different collation order (eg $:/core/modules/startup.js vs. $:/core/modules/startup/commands.js), so it's more robust to explicitly specify the dependency
