Support shebang line (ES14)

[fzn0x]

Shebang line caused several packages issue, the reason is Deno couldn't support running with executable script.

Working in other runtimes:

#!/usr/bin/env bun

console.log("Hello, world!");

#!/usr/bin/env node

console.log("Hello, world!");

In Deno:

#!/usr/bin/env deno

console.log("Hello, world!");

You will receive:

$ ./index.js
error: unrecognized subcommand './index.js'

Usage: deno [OPTIONS] [COMMAND]

For more information, try '--help'.

Deno supports shebangs, see docs for details: https://docs.deno.com/runtime/tutorials/hashbang

Thanks, could we shorthand #!/usr/bin/env -S deno run --allow-env to #!/usr/bin/env deno ?

After shorthand you could handle more permissions if needed

#!/usr/bin/env deno --allow-net

console.log("Hello, world!");

#!/usr/bin/env deno --allow-net

This doesn't work, you need to use -S to pass argument to the interpreter, so the only shortcut would be the removal of run subcommand from the shebang invocation.
