Implement the `OpticalDataPropositionInput` `not`

[christoph-maurer]

When I query https://www.solarbuildingenvelopes.com/graphql/ with

query {
  byNegation: allData(
    where: { not: { gValues: { some: { greaterThanOrEqualTo: 0.5 } } } }
  ) {
    edges {
      node {
        uuid
      }
    }
  }
}

I receive

{
  "errors": [
    {
      "message": "The specified input object field `not` does not exist.",
      "locations": [
        {
          "line": 3,
          "column": 14
        }
      ],
      "path": [
        "byNegation"
      ],
      "extensions": {
        "field": "not",
        "specifiedBy": "http://spec.graphql.org/October2021/#sec-Input-Object-Field-Names"
      }
    }
  ]
}

because not isn't part of type-defs.graphqls).
