Allow adding task name aliases

[xavier-sanna]

It would be great to be able to add task name aliases.

For instance, I have this task named: api:prisma:migrate
I would like to add a shortened alias a:p:m and be able to run the task with both notations.

tasks:
  api:npm:install:
    alias: a:n:i
    cmds:
      -  docker-compose exec api sh -c 'npm install {{.CLI_ARGS}'

It could even be a list of aliases, and not constraint the user to a single naming alterrnative.

tasks:
  api:npm:install:
    aliases:
      - a:n:i
      - npmi
      - etc
    cmds:
      -  docker-compose exec api sh -c 'npm install {{.CLI_ARGS}'

Seems to be a duplicate of #675 & #879, sorry about that
