Convert old GraphQL types to newer type names (Part 2) [RUN AS-IF-FOSS]

What does this MR do?

During conversion to using the new graphql interpreter, I ran across this same issue: https://github.com/rmosolgo/graphql-ruby/issues/2784

So doing all the type conversions here in preparation for !27536 (merged)

• Convert GraphQL::ID_TYPE to GraphQL::Types::ID
• Convert GraphQL::INT_TYPE to GraphQL::Types::Int
• Convert GraphQL::STRING_TYPE to GraphQL::Types::String
• Convert GraphQL::BOOLEAN_TYPE to GraphQL::Types::Boolean
