feat: deno run <task>

[satyarohith]

This PR updates deno run to fallback to executing tasks when there is no script with the specified name. If there are both script and a task with the same name then deno run will prioritise executing the script.

just to be clear, when we talk about tasks, that's the ones in the package.json scripts, and when we talk about scripts that's the deno.json right?

@birkskyum if you run deno run dev and Deno doesn't find file named dev it will try to run deno task dev which takes into account both deno.json and package.json
