`deno task` lets you define tasks with dependencies which must complete first.
Grouping tasks together this way is a handy and popular way to organise your tasks and scripts. But what if you don't want to run another command after your dependencies complete?
Deno v2.2 now lets you do that by allowing you to omit the command from tasks that have dependencies.
`deno task` got other improvements in v2.2 ...too!
