fix(cli): add missing short flag -d for --dataset option

[Ableez]

The publish-images command currently fails when using the -d short flag, even though it is documented and used in task examples. the cli only recognizes the long-form --dataset option, leading to a No such option: -d error.

reproduction
Running the following command triggers the error:

anvil publish-images -d /path/to/dataset -u username --repo anvil-images

actual behavior
the cli returns: Error: No such option: -d

expected behavior
the -d flag should be mapped to the --dataset option to match the documentation and improve cli usability.
