Using SchemaGeneratorHooks to modify type names breaks data fetchers

[HarshDaga]

Library Version
6.4.1

Describe the bug
When using SchemaGeneratorHooks to modify the type names at runtime (yes I know I shouldn't do this but I have a good reason to) the generated schema has the new modified type names but codeRegistry still contains data fetchers for original type names.

This leads to runtime exceptions and the only fix is to add new mappings to the codeRegistry from within the hook.

To Reproduce
An example repo to reproduce the bug (with my workaround for it): https://github.com/HarshDaga/graphql-kotlin-schema-generator-bug

Expected behavior
codeRegistry should be populated using the type names coming from the hook instead of the original type names.

Modifying the type names within SchemaGeneratorHooks will not lead to runtime exceptions.
