[feature request] Add shortcut params for `generate --publish` --> `generate -p`

[mathieu-benoit]

Like it was done there #370 with --image|-i, let's do the same with score-compose generate --publish and have the shortened version score-compose generate -p.

Guidance

That's the line that needs to be updated: https://github.com/score-spec/score-compose/blob/main/internal/command/generate.go#L458

Success criteria

This should work successfully:

make build
./score-compose init
./score-compose generate score.yaml --publish 8080:example:8080

And the -p option should be visible when running the ./score-compose generate --help command.

Assigned to myself, as we have already someone working on this.
