feat: support graphql with pages/cursors

[AndersDJohnson]

We could consider some kind of support for GraphQL and deeply nested page values or cursors.

A shorthand inline query syntax with template literal interpolation using last call's response:

fetchPaginate('https://graphql.example.com', {
  graphql: (previous) => `
    query someQuery {
      products(page: ${previous?.data?.products?.nextPage || 1}) {
        id
        nextPage
      }
    }
  `
})

Or, using a static query but dynamically re-defining variables for each paged call:

const query = `
  query someQuery($page: Int = 1, $type: String) {
    products(page: $page, type: $type) {
      id
      nextPage
    }
  }
`;

fetchPaginate('https://graphql.example.com', {
  graphql: {
    query,
    variables: (previous) => ({
      type: 'blog',
      page: previous?.data?.products?.nextPage
    })
  }
})
