Critical PHP 8.1 deprecation in 3.x Branch

[loopy3025]

Upon upgrade to PHP 8, we have found that we are getting a deprecated function error on many different elements. Here is just one example:

Deprecated function: Return type of Drupal\graphql\Plugin\TypePluginManagerAggregator::getIterator() should either be compatible with IteratorAggregate::getIterator(): Traversable, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in include() (line 5 of modules/contrib/graphql/src/Plugin/TypePluginManagerAggregator.php).

The solution for this seems to be to upgrade webonyx/graphql-php to a version that includes the various php 8.1 compatibility fixes. It seems that the version has been upgraded in drupal/graphql 4.x but there is zero way that we have the time and resources to switch to drupal/graphql 4.x. We have to stay on 3.x due to the huge differences between the two versions.

What we need is a new release for 3.x with the webonyx/graphql-php version upgraded to ^14.8.0. With the issue page having disappeared from drupal.org I'm a bit dubious as to how I can go about contributing to this and testing this.

If you need a schema generator for GraphQL 4 that support almost all features of GraphQL3, have a look at our new module here:
https://www.drupal.org/project/graphql_core_schema/

The generated schema is not 100% compliant, but should support all fields and entities we had in GraphQL 3.

I have tried to use this module https://www.drupal.org/project/graphql_core_schema/ But I am getting an error in the drupal log. So I created the issue: https://www.drupal.org/project/graphql_core_schema/issues/3329691 .
I Hope that it could be solved by maintainers.
Otherwise, I think that we need is a new release for 3.x with the webonyx/graphql-php version upgraded to ^14.8.0.
