[BUG] Dry run: container names in start(ing) progress entries missing first letter

[felixfontein]

Description

When starting a service in dry-run mode, the progress events reporting starting the container are missing its first letter:

 DRY-RUN MODE -  Network compose_default  Creating
 DRY-RUN MODE -  Network compose_default  Created
 DRY-RUN MODE -  Container compose-foobar-2  Creating
 DRY-RUN MODE -  Container compose-foobar-1  Creating
 DRY-RUN MODE -  Container compose-foobar-2  Created
 DRY-RUN MODE -  Container compose-foobar-1  Created
 DRY-RUN MODE -  Container ompose-foobar-2  Starting
 DRY-RUN MODE -  Container ompose-foobar-2  Started
 DRY-RUN MODE -  Container ompose-foobar-1  Starting
 DRY-RUN MODE -  Container ompose-foobar-1  Started

This comes from https://github.com/docker/compose/blob/main/pkg/api/dryrunclient.go#L107 putting containerName into Names, and not "/" + containerName, since getCanonicalContainerName strips the first letter off (https://github.com/docker/compose/blob/main/pkg/compose/compose.go#L135).

Steps To Reproduce

Run docker compose --progress plain up --dry-run --detach (after docker compose down in case something was up) and observe output.
