Do not show label instead of task name in some places like `--list`

Example Taskfile showing the issue

---
version: '3'

vars:
  REPOSITORY_SUBTYPE: config
  REPOSITORY_TYPE: npm

tasks:
  one:
    cmds:
      - task: two
      - pip3 install ansible

  two:
    interactive: true
    label: three
    desc: Hey
    cmds:
      - poetry env info --path
      - poetry --help
      - source "$(poetry env info --path)/bin/activate"

When assigning a label to a task, the task --list is updated with the task with the new label. However, when you attempt to run the task by running task [label_name], task fails to recognize the task.

Also, normally task alphabetizes the list shown in task --list. However, labeled items are not sorted alphabetically.

I propose that we:

1. Allow the user to run tasks by specifying their label name (e.g. task label_name)
2. Alphabetize the task --list with the label names included

Hmm... this actually sounds like more a bug to me where the label should not be shown in same places instead of the real task name, like on --list.

We can't allow tasks to be accessible by its label because the label can contains variables. That would certainly cause problems.
