`-q` option position is inconsistent for the `task` subcommand

[niedzielski]

There is a tiny consistency bug in the CLI's -q option position for the task subcommand specifically. The Deno CLI itself (deno [OPTIONS] [SUBCOMMAND]) supports -q for most (all?) subcommands except task.

Consider the following:

$ echo '{"tasks": {"echo": "echo"}}' > deno.json
$ deno -q task echo
Task not found: task
Available tasks:
- echo
    echo

Instead, the -q option must appear after the subcommand:

$ deno task -q echo

This is inconsistent with most other subcommands and the the CLI help documentation. Eg, fmt works as expected:

$ deno -q fmt

The expected supported format is always deno [OPTIONS] [SUBCOMMAND]. deno -q task, in this case.

After a first look, this seems to have been introduced by #14567

log_level is set correctly, but task_parse() always uses argv[2] as the task name. This can be seen in the output

$ deno --quiet task echo
Task not found: task
$ deno --quiet --unstable echo
Task not found: --unstable

There is code to get the index of the task name in argv (or raw_args), but it isn't working as intended.

I'd like to work on this issue
