Superfluous underscore suffixes 'schema' field name

[kingtistel]

Describe the bug
From the json schema a property named 'schema' was created as a field named 'schema_'.

To Reproduce

Example schema:
https://schema.getpostman.com/json/collection/v2.1.0/collection.json

Used commandline:

$ datamodel-codegen --url https://schema.getpostman.com/json/collection/v2.1.0/collection.json --output-model-type typing.TypedDict --output postman_td.py

and equally:

$ datamodel-codegen --url https://schema.getpostman.com/json/collection/v2.1.0/collection.json --output-model-type dataclasses.dataclass --output postman_dc.py

Expected behavior
Expected that the 'Info' class would have a field named 'schema'. Instead it has a field named 'schema_'.

Version:

• OS: macOS 14.3
• Python version: 3.11.7
• datamodel-code-generator version: 0.25.3
