[BUG] [PYTHON] A schema named Schema with type array generates broken model null<SchemaInner> in 7.2, works in 6.0

Bug Report Checklist

Description

    QueueTuple:
      type: array
      description: ...
      items:
        oneOf:
          - type: number
          - type: string
          - $ref: "#/components/schemas/Prompt"
          - $ref: "#/components/schemas/ExtraData"

A schema of type: array with a oneOf in items produces snippets of broken Python code like:

from comfy.api.models.null<queue_tuple_inner> import null<QueueTupleInner>
...

class QueueTuple(null<QueueTupleInner>):
    """
    The first item is the queue priority The second item is the hash id of the prompt object The third item is a Prompt The fourth item is optionally an ExtraData The fifth item is optionally a list of \"Good Outputs\" node IDs. 
    """ # noqa: E501
    __properties: ClassVar[List[str]] = []

Steps to reproduce

See Collab notebook here https://colab.research.google.com/drive/18sXET4mnQLMrsxru2vumN7iuk1fVJEVr?usp=sharing

git clone https://github.com/hiddenswitch/ComfyUI.git --branch wip/api repro
git clone https://github.com/OpenAPITools/openapi-generator.git --depth=1
(cd openapi-generator && ./mvnw clean install -Dmaven.test.skip=true -Dmaven.javadoc.skip=true -q &>/dev/null)
(cd repro && java --add-opens java.base/java.io=ALL-UNNAMED --add-opens java.base/java.util=ALL-UNNAMED --add-opens java.base/java.lang=ALL-UNNAMED -jar ../openapi-generator/modules/openapi-generator-cli/target/openapi-generator-cli.jar generate --input-spec ./comfy/api/openapi.yaml --global-property models --config ./comfy/api/openapi_python_config.yaml)

cat ./repro/comfy/api/models/queue_tuple.py

Observe queue_tuple has content like

from comfy.api.models.null<queue_tuple_inner> import null<QueueTupleInner>
from typing import Optional, Set
from typing_extensions import Self

class QueueTuple(null<QueueTupleInner>)

which is not valid Python and indicates a bug.

Suggest a fix

Not sure what the underlying issue is, are Array schemas unexpected? this works in 6.x.

Reproduce the regression with the QueueTuple schema from the linked OpenAPI declaration using the Python client generator on 7.2.0 or current master. Compare the generated import and class names with the reported broken null output; done means valid Python model code is generated for the array with oneOf items.
