Don't run setup-docker because docker is already installed

and that action fails with:

```
  The following packages will be DOWNGRADED:
  docker-ce docker-ce-cli
0 upgraded, 0 newly installed, 2 downgraded, 0 to remove and 11 not upgraded.
E: Packages were downgraded and -y was used without --allow-downgrades.
```
