add dashboardaddWidgetsToPage and dashboardUpdatePage support in dashboards

[smcavallo]

Feature Description

Add support for these missing operations to dashboards
https://docs.newrelic.com/docs/query-your-data/explore-query-data/dashboards/dashboards-api/#page-operations
dashboardUpdatePage()
dashboardUpdateWidgetsInPage()
dashboardAddWidgetsToPage()
and the additional type of DashboardUpdatePageInput

It may be as simple as adding to .tutone.yaml

    mutations:
      - name: dashboardAddWidgetsToPage
      - name: dashboardUpdatePage
      - name: dashboardUpdateWidgetsInPage

Describe Alternatives

These are all available in the nerdgraph API and in fact exist in the schema.json file created when you run make generate - they just don't exist in .tutone.yaml or dashboards_api.go

Additional context

I tried to add support for this myself in .tutone.yaml but make generate does not work locally - it is generating the types incorrectly and then failing due to errors in the types. It is using the default version of the tutone generator which is tagged as "dev"
