Screenshots or screen recordings

No UI changes.

How to set up and validate locally

1. Visit GraphQL explorer: http://127.0.0.1:3000/-/graphql-explorer
2. Execute modification statement:

   mutation setSortPreference($input: UserPreferencesUpdateInput!) {
     userPreferencesUpdate(input: $input) {
       errors
       __typename
       userPreferences {
         visibilityPipelineIdType
       }
     }
   }

   Variables

   {
     "input": {
       "visibilityPipelineIdType": "id" # can be changed to "iid"
     }
   }

3. Expected effect: GraphQL returns the variable "id"(Screenshot 1), and the same change effect can be seen in database(Screenshot 2)
