### What part(s) of the page would you like to see updated?

https://github.com/dbt-labs/dbt-core/issues/7660#issuecomment-1559357223 has a useful example using `json.tool` to pretty-print JSON formatted output. Although I prefer using [`jq`](https://stedolan.github.io/jq/) instead, `json.tool` is shipped along with Python, so it is quicker for most folks to use.

`json.tool` (and `jq`!) would be good to document in our docs to help people visualize their resource properties.

### `json.tool`
```shell
dbt -q ls --output json --resource-type source | python -m json.tool --json-lines
```

```json
{
"name": "some_table_1",
"resource_type": "source",
"package_name": "my_project_name",
"original_file_path": "models/some/very/deeply/nested/folder/_sources.yml",
"unique_id": "source.my_project_name.oba_postgres_public.some_table_1",
"source_name": "oba_postgres_public",
"tags": [],
"config": {
"enabled": true
}
}
{
"name": "some_table_2",
"resource_type": "source",
"package_name": "my_project_name",
"original_file_path": "models/some/very/deeply/nested/folder/_sources.yml",
"unique_id": "source.my_project_name.oba_postgres_secure_db.some_table_2",
"source_name": "oba_postgres_secure_db",
"tags": [],
"config": {
"enabled": true
}
}
```

### `jq`

Prerequisite: [install `jq`](https://stedolan.github.io/jq/download/)

```shell
dbt -q ls --output json --resource-type source | jq .
```
