Calling `json()` no longer calls `dict()`

[andreyfedoseev]

According to the documentation:

Typically, .json() in turn calls .dict() and serialises its result.

This behavior has been changed in 1.9.0, and calling .json() doesn't call .dict() anymore.

I consider this a breaking change because it breaks a documented feature. Also, the documentation hasn't been updated to reflect this change.

Bug

Output of python -c "import pydantic.utils; print(pydantic.utils.version_info())":

1.9.0

import pydantic

class MyModel(pydantic.BaseModel):
    
    spam: int

    def dict(self, **kwargs):
        d = super().dict(**kwargs)
        d["ham"] = 2
        return d

MyModel(spam=1).json()

# expect to get: {"spam": 1, "ham": 2}
# actually get: {"spam": 1}

Unfortunately, this was a breaking change. I've created a PR to update the documentation
