[Core feature] Pydantic BaseModel V2 in Dataclass

### Motivation: Why do you think this is important?

Some users want the below example works in a task/workflow.
```python
from dataclasses import dataclass, field

# Define InnerBM using Pydantic BaseModel
class InnerBM(BaseModel):
a: int = -1
b: float = 3.14
c: str = "Hello, Flyte"
d: bool = False

# Define the dataclass DC
@dataclass
class DC:
a: int = -1
b: float = 3.14
c: str = "Hello, Flyte"
d: bool = False
inner_bm: InnerBM = field(default_factory=lambda: InnerBM())
```

### Goal: What should the final outcome look like, ideally?

These 2 cases should work.
