Expose fieldsets

I took a look at this. I think it is almost done, but somehow there is something missing. I get this error when visiting the explorer:

GraphQL\Error\Error: Type "WebformElementWebformFieldset" not found in document. in GraphQL\Utils\BuildSchema::GraphQL\Utils\{closure}() (line 149 of /app/vendor/webonyx/graphql-php/src/Utils/BuildSchema.php).

Ok, found the issue. I chose the wrong name in the schema.

The fieldsets are being exposed properly for me.

Thanks a lot for this. I updated the MR to account for the removal of the metadata subfield (ref. ✨ Remove Metadata subfields Fixed ) and fixed the test coverage.

Automatically closed - issue fixed for 2 weeks with no activity.
