example config for chef uses wrong syntax

[ananke]

The example configuration https://cloudinit.readthedocs.io/en/latest/topics/examples.html#install-and-run-chef-recipes has a missing YAML key:

```
# Key from https://packages.chef.io/chef.asc
apt:
  sources:
    source1: "deb http://packages.chef.io/repos/apt/stable $RELEASE main"
    key: |
```

Should be instead:

```
# Key from https://packages.chef.io/chef.asc
apt:
  sources:
    source1:
      source: "deb http://packages.chef.io/repos/apt/stable $RELEASE main"
      key: |
``

Cheers!
