Fix passing input parameters in a form of JSON string via GraphQL Gateway

[pkosiec]

Description

Changes proposed in this pull request:

• Investigate and fix issue related to passing input with JSON string
• Use forks for Nautilus GraphQL and GraphQL Go

The problem was down in the dependency tree:

nautilus/gateway -> nautilus/graphql -> graphql-go/graphql

See the fix in the underlying library graphql-go:
Issue: graphql-go/graphql#586
Pull request: graphql-go/graphql#587

I also updated my original issue on Nautilus Gateway: nautilus/gateway#121

How to test it

Run the local cluster on this branch:

make dev-cluster

Navigate to https://gateway.voltron.local and run the following GraphQL query:

mutation CreateAction {
  createAction(
    in: {
      name: "sample"
      actionRef: {
        path: "cap.interface.productivity.jira.install"
      },
      input: {
        parameters: "{\"input1\": \"foo\", \"input2\": 2, \"input3\": { \"nested\": true }}",
        typeInstances: [
          { name: "foo", id: "fee33a5e-d957-488a-86bd-5dacd4120312" }
          { name: "bar", id: "563a79eb-7417-4e11-aa4b-d93076c04e48" }
        ]
      }
      dryRun: true
    }
  ) {
    name
    createdAt
    actionRef {
      path
      revision
    }
    renderedAction
    cancel
    run
    dryRun
    input {
      parameters
      typeInstances {
        name
        typeRef {
          path
          revision
        }
        id
        optional
      }
    }
    output {
      typeInstances {
        name
        typeRef {
          path
          revision
        }
        id
      }
    }
    renderingAdvancedMode {
      enabled
      typeInstancesForRenderingIteration {
        name
        typeRef {
          path
          revision
        }
        id
        optional
      }
    }
    renderedActionOverride
    status {
      condition
      timestamp
      message
      runner {
        status
      }
      cancelledBy {
        username
        groups
        extra
      }
      runBy {
        username
        groups
        extra
      }
      createdBy {
        username
        groups
        extra
      }
    }
  }
}

Aaand... it works now! 🎉
