Minor Changes

• #7916 4686454 Thanks @andrewmcgivery! - Add hideSchemaDetailsFromClientErrors option to ApolloServer to allow hiding 'did you mean' suggestions from validation errors.

  Even with introspection disabled, it is possible to "fuzzy test" a graph manually or with automated tools to try to determine the shape of your schema. This is accomplished by taking advantage of the default behavior where a misspelt field in an operation
  will be met with a validation error that includes a helpful "did you mean" as part of the error text.

  For example, with this option set to true, an error would read Cannot query field "help" on type "Query". whereas with this option set to false it would read Cannot query field "help" on type "Query". Did you mean "hello"?.

  We recommend enabling this option in production to avoid leaking information about your schema to malicious actors.

  To enable, set this option to true in your ApolloServer options:

  const server = new ApolloServer({
    typeDefs,
    resolvers,
    hideSchemaDetailsFromClientErrors: true,
  });
