Is your feature request related to a problem? Please describe.
The current behavior generates unhelpful enumerated class names, like Address1, Address2, Address3 when the source has multiple definitions for Address.

The current codebase includes a comment:

# TODO: Improve naming for nested ClassName

Describe the solution you'd like
The enclosed code is a workaround. We define PatchJsonSchemaParser which can be used like this:

from datamodel_code_generator import generate

with patch('datamodel_code_generator.parser.jsonschema.JsonSchemaParser', PatchJsonSchemaParser):
      generate(...)

This generates more appropriate and verbose classnames, like CustomerAddress, UserAddress, VendorAddress.

Describe alternatives you've considered
Ugly regex on the output

Additional context
This seems to be an FAQ for this library: https://github.com/koxudaxi/datamodel-code-generator/discussions/1792

Here is the proposed workaround: patch_datamodel_code_generator.py (remove .md suffix as github won't accept a .py file here)
