Description

Can't create any schemas at all.

```python
class Price(db.Model):
id = db.Column(db.Integer, primary_key=True)
name = db.Column(db.String(128), index=True)

class PriceSchema(ma.SQLAlchemyAutoSchema):
class Meta:
model = Price
```

This raises the following error:
```
TypeError: Schema.__init__() got an unexpected keyword argument 'include_data'
```

Have also tried with `ma.SQLAlchemySchema`.

Installed:
flask version : 2.0.1
flask_marshmallow version : 0.14.0

Research direction

Start by reproducing the error with the provided Price model and PriceSchema examples using SQLAlchemyAutoSchema and SQLAlchemy. Check the installed Flask-Marshmallow and Marshmallow integration entry points for how schema initialization handles include_data. Done means both schema classes can be instantiated without the unexpected-keyword TypeError.
