### Description This PR improves error messages in our metadata API by displaying a message with the name of the failing command and a link to our documentation. Furthermore, it harmonizes our internal uses of `withObject`, to respect the convention of using the Haskell type name, now that the Aeson error message is displayed as an "internal error message". https://github.com/hasura/graphql-engine-mono/pull/1905 GitOrigin-RevId: e4064ba3290306437aa7e45faa316c60e51bc6b6
