Description

Update WPGraphQL to the latest version (v1.22.1). Note there was a previous PR attempting an update with git subtree, but that was abandoned for dependency difficulties.

Steps to Test

1. Install and activate the plugin.

2. Go to Admin -> Settings -> VIP Decoupled and ensure "WPGraphQ" and "VIP Block Data API" are enabled.

3. Go to Admin -> GraphQL -> GraphiQL IDE and try a block query against an existing post (431 below):

   query NewQuery {
     post(id: 431, idType: DATABASE_ID) {
       blocksData {
         blocks {
           id
           name
           innerBlocks {
             attributes {
               name
               value
             }
             id
             name
             parentId
           }
         }
       }
     }
   }
