Deno task files

[Conaclos]

It could be nice to be able to write a multi-line task in a task file instead of one-liner task in the deno configuration file.

For instance a file named build:

#!deno task

command1:
command2:
command3:
...

instead of:

{
  "tasks": {
    "build": "command1; command2; command3; ..."
  }
}

The task file could be run as follows:

deno task ./build

Because we use a shebang, we could also write:

./build

This was asked previously and our recommendation for this is to just write JS/TS script that needs to do a lot of commands and call that script from deno task, like so:

// build.js
command1;
command2;
command3;

{
  "tasks": {
    "build": "deno run build.js"
  }
}
