Additional context
The generated function signature for _get_kwargs looks like this:

def _get_kwargs(
    has_default: str = 'default_value',
    no_default: int,
) -> dict[str, Any]:

The issue does not occur for query parameters, as the generator emits keyword-only arguments (*) for them. It only occurs for path parameters, which are emitted as positional-or-keyword arguments.

使用报告中的最小 OpenAPI 规范重现该问题，并检查构建路径参数的生成 _get_kwargs 签名的生成器路径。通过成功生成客户端，并验证必需的路径参数可以位于具有默认值的参数之后且不会产生 Python SyntaxError，来确认修复有效。
