Fix output of cookbook list/show (#13654)

This PR turns the output from the following:
```json
$ knife cookbook list -a -F json
[
  "7-zip                       1.0.2",
  "api_docs                    0.1.0",
  "apt                         1.1.1",
  "ark                         4.0.0  3.1.1  0.9.0  0.3.0",
  "audit-cis                   0.4.0",
  "authenticator               0.1.5  0.1.4",
  "aws-static-ip-ha            0.1.0",
  "aws-tools                   0.0.5"
]
```
to this
```json
$ knife cookbook list -a -F json
{
  "7-zip": [
    "1.0.2"
  ],
  "api_docs": [
    "0.1.0"
  ],
  "apt": [
    "1.1.1"
  ],
  "ark": [
    "4.0.0",
    "3.1.1",
    "0.9.0",
    "0.3.0"
  ],
  "audit-cis": [
    "0.4.0"
  ],
  "authenticator": [
    "0.1.5",
    "0.1.4"
  ],
  "aws-static-ip-ha": [
    "0.1.0"
  ],
  "aws-tools": [
    "0.0.5"
  ]
}
```

This has a potential of breaking peoples script if they adjusted to the broken format, that is why this is marked as a breaking change.

This brings the output of the following in line with other listings coming out of chef
