fix: deprecation warning

[josephfusco]

This PR includes cherry picked changes from develop that were missing from master in order to resolve https://github.com/wp-graphql/wp-graphql-acf/issues/382

[jasonbahl]

The Docker environment for automated tests is currently broken and we will not be fixing it in this repo as it will be archived in favor of the re-architected version of the WPGraphQL for ACF plugin: https://github.com/wp-graphql/wpgraphql-acf

To test this functionality I:

• imported the following ACF Field Group: acf-export-2024-07-22.json
• published a post with values in the fields
• queried for the fields, executing the deprecated resolvers:

{
  post(id: 7229, idType: DATABASE_ID) {
    id
    databaseId
    uri
    acfDeprecationTest {
      imageFieldTest {
        sourceUrl
      }
      taxomomyFieldTest {
        name
        slug
      }
    }
  }
}

Data is returned as expected and the deprectated methods are no longer executed.
