Dataclass serializer generation fails in 3.14

[HC4L]

Describe the bug

Using uadiscover or any other method to open a connection to a server.
When creating the serializer for the class asyncua.ua.uaprotocol_hand.Hello a "property" field is included in the fields to create serializers for.
I think there is a change in 3.14 for the internal representation of dataclasses.
Works in 3.13.

To Reproduce

Use uadiscover or the default example to connect to a server.
