`Input should be a valid string` for integer keys in openapi.yaml

[mymindwentblvnk]

Describe the bug
When generating classes from openapi.yaml with integers as keys (e.g. 200), I get the error:

paths./api/events.get.responses.200.[key]
  Input should be a valid string [type=string_type, input_value=200, input_type=int]
    For further information visit https://errors.pydantic.dev/2.12/v/string_type

Is there a chance to ignore those errors and fall back to string for integer keys?
