chore(deps): update actions/setup-go action to v6

This patch extends dcmerge to support the command attribut of a defined service.
For example:

```yaml
services:
  busybox
    command: [ "/usr/bin/cp", "--recursive", "--force", "/tmp/bar.txt", "/tmp/foo.txt"]
    image: library/busybox:latest
```

The command attribute is interpreted as a whole. This means that individual
arguments are not merged as a comparison, as this would change the meaning of
the command attribute.
