fix: Preserve class names when generating models from JSON Schema 202…

[koxudaxi]

Fix: #2032

This pull request includes changes to improve the handling of references in the datamodel_code_generator and adds new tests to ensure the functionality works as expected. The most important changes include modifying the add_ref method to handle trailing hash characters and adding new test cases for the ModelResolver class.

Improvements to reference handling:

• datamodel_code_generator/reference.py: Modified the add_ref method to use rstrip('#') instead of slicing to remove trailing hash characters from references.

New test cases:

• tests/test_reference.py: Added import for ModelResolver and new test cases to verify the add_ref method handles references with and without trailing hash characters correctly. [1] [2]
