Multiline syntax

Copy `minimal.yaml` into `multiline.yaml` and add other steps with commands `sleep 20`, `echo Waking Up`. The multiline syntax is the following:
```
-
    run: |
        <command 1>
        <command 2>
        <command 3>
```
Now you will see 2 independent workflows triggering with each push in your repository. Check it in Actions.
