Better aliasing for includes

[titpetric]

I want to import all the targets for an included taskfile into the current namespace.

includes:
  services:
    taskfile: Taskfile.services.yml
    aliases: [""]

The aliases feature exists, however when setting it to empty it still includes the :, making all of the alias still have the delimiter as the prefix. The change checks for an empty namespace, and removes a redundant sprintf call in the same function.

Before the change:

* services:build:       docker compose build                                       (aliases: :build)
* services:down:        docker compose down                                        (aliases: :down)
* services:logs:        docker compose logs etl -f                                 (aliases: :logs)
* services:mysql:       docker compose exec -it etl-db mysql -u etl -petl etl      (aliases: :mysql)
* services:up:          docker compose up -d --wait                                (aliases: :up)

After the change:

* services:build:       docker compose build                                       (aliases: build)
* services:down:        docker compose down                                        (aliases: down)
* services:logs:        docker compose logs etl -f                                 (aliases: logs)
* services:mysql:       docker compose exec -it etl-db mysql -u etl -petl etl      (aliases: mysql)
* services:up:          docker compose up -d --wait                                (aliases: up)

I was literally looking for a solution like this yesterday!

I think flattening is the behavior you're looking for: #273, #1704

This has been long requested and is probably coming soon. I don't think alias is the right way to do this. In fact, we should probably raise an error when someone does alias: "".
