### What
Consider the following query:

```graphql
query {
institution_in_a_country_with_a_city_named_stockholm: InstitutionMany(
    where: { location: { country: { cities: { name: { _eq: "Stockholm" } } } } }
  ) {
    id
    location {
      country {
        cities {
          name
        }
      }
    }
  }
}
```

We are filtering by the object field `name` inside the nested array
`cities` field, that itself is nested inside `location.countries`. This
previously did not work because the nested field pathing sent to the
connector was incorrect.

### How

The code did not correctly set the `column` vs the `field_path` on
`Expression::LocalNestedArray`. This has been fixed.

The test postgres DB schema has been updated to add the `cities` array
in order to facilitate testing this.

The justfile script that is used to update the postgres schema in test
DataConnectorLinks got modifies as the schema started to exceed the size
limit that can be sent via command line args. It now writes the schema
and capabilities to temporary files and feeds them into `jq`, instead of
using command line args to pass in schema and capabilities.
