Fix pyright 1.1.407 typing errors in azure-health-deidentification

[Copilot]

Pyright 1.1.407 tightened inference on dict.get(key, default) — when the default is data.__class__, it now infers type | None instead of type, causing issubclass(enum_type, Enum) to fail type checking.

Changes

• _serialization.py / _utils/serialization.py: Wrap the dict.get default with cast(type, ...) so pyright resolves enum_type as type.

# Before
enum_type = self.dependencies.get(data_type, data.__class__)

# After
enum_type = self.dependencies.get(data_type, cast(type, data.__class__))

Consistent with the fix already applied in other SDK packages (e.g., azure-mgmt-containerservice).

Automated Fix: This PR was automatically generated by Copilot in response to a vnext compatibility issue.
