In https://github.com/pydantic/pydantic/pull/10029, pydantic made an improvement to its generated JSON schemas (OpenAPI schemas). The previous and new generated schemas both meet the schema spec. When we parse the OpenAPI schema to generate node templates, we use some typeguard to narrow schema components from generic OpenAPI schema objects to a node field schema objects. The narrower node field schema objects contain extra data. For example, they contain a `field_kind` attribute that indicates it the field is an input field or output field. These extra attributes are not part of the OpenAPI spec (but the spec allows does allow for this extra data). This typeguard relied on a pydantic implementation detail. This was changed in the linked pydantic PR, which released with v2.9.0. With the change, our typeguard rejects input field schema objects, causing parsing to fail with errors/warnings like `Unhandled input property` in the JS console. In the UI, this causes many fields - mostly model fields - to not show up in the workflow editor. The fix for this is very simple - instead of relying on an implementation detail for the typeguard, we can check if the incoming schema object has any of our invoke-specific extra attributes. Specifically, we now look for the presence of the `field_kind` attribute on the incoming schema object. If it is present, we know we are dealing with an invocation input field and can parse it appropriately.
