composition/programmes becomes very unstable when using the preview API

[MortenHofft]

There is a lot of error 500's when using the preview API. At best you get a result every 10 times you try. Might be as simple as we are spamming the service.

E.g. on https://graphql.gbif-dev.org/graphql

  query Programme($key: String!) {
    programme(id: $key, preview: true) {
      title
      excerpt
      blocks {
        ...BlockItemDetails
      }
    }
  }

  fragment BlockItemDetails on BlockItem {
    __typename
    ... on HeaderBlock {
      id
      ...HeaderBlockDetails
    }
    ... on FeatureBlock {
      id
      ...FeatureBlockDetails

    ... on FeaturedTextBlock {
