EASI-3510

Changes and Description

• upgrade gqlgen to v0.17.40
• changes that led to this not being a simple version bump: Map based input types fields are now coerced to the right type 99designs/gqlgen#2830
• in places where we used map[string]interface{} as the @goModel, the scalars were coming through as strings instead of their declared scalar types, such as UUID, for example. This was fixed in gqlgen, but our resolvers were designed with this pattern (always having strings) in mind, so some functionality was updated in this PR to account for the types no longer being strings. Inputs below are where this is relevant
  • input TRBRequestChanges
  • input UpdateTRBRequestFormInput
  • input UpdateTRBAdviceLetterInput
  • input UpdateTRBAdviceLetterRecommendationInput

  • updating an advice letter recommendation
  • adding subject areas to a TRB request as you are creating it
