$ref in path parameters doesn't seem to work

Describe the bug
If a get path has a parameter using $ref to point to #/components/parameters, the generated API lacks the corresponding kwarg. If one "hoists" the indirect parameter up into the path's parameters, it works as expected.

To Reproduce
See this repo for a reproducible example.
And see this repo for the same schema without the $ref, working as expected.

Expected behavior
I expect to see the optional page kwarg in both generated APIs.

I see this in the $ref example:

def sync(
    *,
    client: Client,
) -> Optional[List[str]]:

and this in the noref example:

def sync(
    *,
    client: Client,
    page: Union[Unset, None, GetTestPage] = UNSET,
) -> Optional[List[str]]:

OpenAPI Spec File
A link to your openapi.json which produces this issue.

Desktop (please complete the following information):

• OS: Microsoft Windows 10 Pro 10.0.19044 Build 19044
• Python Version: 3.9.12
• openapi-python-client version 0.11.1

从可复现的 openapi-ref-issue 仓库中链接的 test-schema.yaml 开始，并使用报告的 openapi-python-client 版本运行生成器。将生成的 sync 入口点与 noref 示例进行比较，重点关注参数 $ref 的解析。当生成的 API 在引用参数的情况下也包含可选的 page kwarg 时，即表示完成。
